Engine misfiring is common in engines, but diesel repair mesa wants you to know that the good news is that they are usually easy to diagnose.

Diesel engines ignite the fuel through pressure since gas engines use a spark from the ignition system. With the misfiring of diesel engines, the ignition system is the first place to start looking for errors. The following appropriate steps to diagnose the problem include checking the ignition wires, the spark plugs, the rotor/distributor components, and the ignition coil. The spark resulting from the ignition will often not transfer appropriately because the previous parts wear out significantly over time. The inability to ignite the air/fuel mixture in the combustion chambers will cause the engine to misfire.

If you are experiencing misfires with your diesel engine, follow these steps:

  1. Ensure you are using high-quality diesel. Check diesel fuel to verify that the source does not contain contaminants, including water, dirt or oil.
  2. Replace the fuel filters as necessary and drain the water from the network using water and fuel separator.
  3. Test the fuel line for leaks.
  4. Fourth, check for low fuel supply pressure.
  5. Fifth, check the curves or failures in the fuel line and the transfer of the pump.
  6. Check if there is a suction tube (in the fuel tank) or a conductive suction.
  7. Check for air in the fuel system and check the fuel pressure.
  8. If the pressure is lower than specified, replace the fuel filters.
  9. Check the free back box, if it is low, replace the transfer pump.
  10. If all the above cannot diagnose the misfiring, there are other possible additional causes of the defect:
  • Incorrect adjustment of the LED valve
  • The valves do not sit correctly.
  • Defective pump unit or fuel injection nozzles

Diagnosing and correcting any errors that occur along the way can be much more frustrating than trying to find out why the engine misfires. However, there are some similarities between trying to determine why it failed.

Does your car tend to surge forward when you step on the gas? The information I am going give can be applied to any vehicle experiencing the same problem. A normal car should accelerate steadily from rest until you gain peak speed, If your engine has an irregular acceleration read on for some causes and solutions. You can always bring your car for Auto Repair San Francisco and have our expert technicians troubleshoot these issues for you.

The following are the causes and solutions of engine surge.

Failing fuel pump and regulator

Most fuel injected vehicles have an injector pump and regulator assembly that helps in fuel delivery to the engine. In order to inspect the pump and regulator, make sure the vehicle is on a flat ground, Attach a pressure gauge to the fuel test port, put the ignition key to the “ON” position. The gauge should jump up to 45 psi and 58 psi. With the engine running the pressure should drop to 5 psi and 52 psi. If this test fails you need to check your fuel delivery system.

Clogged Fuel Filter

A fuel filter ensures clean fuel is delivered to the engine; it is normally replaced within an engine tune-up. Some fuel filters are located inside the fuel tank and are designed to last the entire lifespan of the car. Replacing your filters could fix the problem.

Faulty Mass Air Flow Sensor

This sensor measures air intake volumes while sending signals to the engine in order to determine the engine loads and speed. The sensor may need to be cleaned or replaced.

Cracks in the vacuum line

Hood temperature can result in too hard and brittle vacuum lines; this causes cracks which leak some intake pressures. This could cause some surges. Replacing the broken vacuum lines is a quick fix.

Torn air intake hose

The air intake hose transfers engine intake air volume into the throttle actuator a torn one will develop engine surge. This is fixed by replacing the hose.

Faulty catalytic converter

It is normally used to eliminate air pollution by reducing emissions if it fails it might cause a blockage in the exhaust system. The solution involves replacing the catalytic converter.

Worn out clutch assembly

Wearing out of the clutches can cause a slip which causes a surge sensation. In an automatic transmission, this can be solved by replacing the old fluid while manual transmission involved replacing the entire assembly.

Most surges are caused by a fault in the fuel delivery system and drivetrain failures. In order to fix a surge, you need to inspect the car and determine the fault.  If the engine light is on connect a trouble code reader to diagnose engine fault.

Or take your car to your mechanic and let them do the troubleshooting for you.

Overheating is a common problem among the older cars which used to have steel engines, they got heated up quickly, but the current scenario has changed drastically with the use of modern technology in engines. But, you can never be 100% sure in the case of machines. As there are various factors that contribute to overheating in cars, Newman’s Auto brings you the following list of  preventive measures that can be helpful for you.

1. Keep a regular check on radiator caps

The radiator caps are specially designed to keep the radiator cool, maintaining an optimum pressure in the system, not allowing the coolant to boil. But when the cooling system fails and undesirable pressure is formed inside the system, it makes the coolant to boil. Boiling of coolant increases air and bubbles which aren’t good at conducting heat. Hence, the generated heat cannot be transferred out from the engine, causing overheating in cars.

2. Decrease in coolant levels

One of the main reasons for overheating in cars is a decrease in coolant level. This may be either due to leakage in radiator, water pump, cylinder heads or the freeze plugs. Another reason for low coolant level could be irregularities in servicing of your car. Keep the radiator full with coolant and keep a regular check on the levels. In case of emergency, you can fill the reservoir with tap water which might prevent your car from overheating. But, replacing it with proper coolant is advisable as tap water is only a temporary solution.

3. When the electric fan fails

An unexpected failure in electric fans can cause your car to overheat. The fan provides cool air to the radiator and keeps your car at an optimum temperature, preventing it from exceeding the heat in your car. A small stone, causing a blockage could be the reason for electric fan failure. You may need to contact a local mechanic for assistance to resolve the issue.

4. Issue with the water pump of your car

Water pump of your car gets damaged if there is a breakage or a seal leakage occurs inside the pump which ultimately leads to overheating. The only solution is to replace the water pump once it is damaged as it cannot be fixed or repaired.

5. Cleaning your car’s radiator

Any kind of adulterants around the radiator can cause a steep decline in cooling of your car either new or old. Hence a simple cleaning of the radiator both from inside and outside is necessary in order to keep the system going for long. The inside cleaning can be done with every coolant change by flushing the old one and by draining it with water, preferably distilled water which could help in preventing rust deposits.


If you haven’t seen it, you know about it, the dreaded Check Engine Light.  But what does it mean if the. Check Engine Light starts flashing?

A flashing indicator light is seriously trying to get your attention.   When a car check engine light flashes in your dashboard this brings in a sinking feeling in the pit of the stomach. This could mean a serious and very costly problem, maybe the catalytic converter has gone bad or there is a loose gas cap or maybe the oxygen sensor has failed to work.  You should pull over as soon as it is safe and contact your mechanic or smog shop.  A flashing light indicates a condition that could cause serious damage to your engine.

When the car check engine light is only a steady illumination you have a little more time to diagnose the issue.  You should give your mechanic a call right away or if you are handy with auto repairs there are some diagnostic you can do yourself.

Causes Of Car Check Engine Light.

There are many causes of check engine light. The following are just some of the causes:

  • Oxygen sensor getting covered with oil ash thus reducing oxygen and fuel mixture. This further leads to gas mileage and increased emissions.
  • Faulty or loose gas caps.
  • Failure of the catalytic convertors.
  • Improper installation of the air filter which leads to mass airflow sensors fail.
  • A failing spark plug.

How To Repair Your Car To Ensure That The Car Check Engine Light Turns Off.

Detection of an issue by the computer results to flashing of the car check engine light. Once this happens you need to do the repair in your and check what the problem is. The following are the simplest and cheapest ways of repairing your car to ensure that the check engine light keeps off.

Ensure that you use a scan tool.

You have to connect the scan tool to the OBD-II and turn the ignition switch on. Press the red button to view errors in your car, remove the error code and press the erase button to remove the error code.

Try out the battery disconnecting technique.

Disconnect the car battery cables, drain out the remaining electricity and wait for some time before reconnecting back the battery.

Turn the ignition on and off severally.

When doing this do not disconnect the battery. Do it repeatedly until you are satisfied if the problem was here or somewhere else

Don’t force the check engine light to go off, allow it to go off by itself.

Ensure that once the check engine light flashes you thoroughly investigate the problem, if you ignore this issue you can end up causing more damages to your engine.

Use these cheap and easy ways to detect the problem in your car and get it repaired or fixed.

Have you ever heard weird noises coming out of your braking system when you apply the brakes? This could be very annoying but it is simply a way in which your car is trying to communicate with you. Much of brake noise would range from: grinding, thumping from the rear, squeaking or scraping, but all add up to one thing; your brakes need a checkup and possible repairs. RSC Automotive Repair San Clemente  brings you the following list of the most common problems that cause brake noise and how to fix them.

Grinding noise when you apply your brakes

A grinding noise is very exasperating and alarming, when you hear this you need to stop driving immediately it is usually caused by a lack of brake pad material. Brake pads usually wear out with time and they require replacement.  If fixed when you first notice the problem, the repair isn’t expensive.

Ignoring a grinding noise can result in severe damages that will require replacing the disc, pads and in some scenarios the calipers. This is much more expensive than just replacing the pads alone. If your brakes are grinding make an appointment with your repair shop.

Squeaking noise

A brake squeak can be very disturbing, besides it might be a significant danger. Most common brake squeaks are caused by menial pads. Cheap brake pads have metal flakes in the pad material, pressing the brake pedal drags the flakes along the disc and thus squeaking. The best way to avoid this is by using quality brake pads and discs.

Another cause of a squeak is the wear indicator, usually, a small metal tab fastened to the brake pad, you hear a squeak while driving down the road.  The squeak goes away when you press the pedal. Solving this involves just removing the worn out pads and replacing with new ones.  This is just an indicator that it is time for brake pad replacement.

Thumping noise from the rear

Cars with drum brakes in the back tend to have this kind of noise. It is usually caused by an uneven braking surface in the drum. Replacing the drums fixes this, you can also try sanding away the uneven surface with 40 grit, and this could come in as a cheap fix.

If you are hearing noises when you are stopping, take your car to you mechanic so they can troubleshoot and help fix the noises coming from your brakes.

When a car pulls to the right or left when braking, it is a clear indication of a potentially dangerous situation, which should be dealt with as soon as possible. The technicians at Hillman Family Automotive know that brakes are among the crucial systems in the car that should be working correctly at all times.

At times when a car pulls to the right or left when brakes are applied, it may not be a serious situation.

There are two types of brake systems namely the disc and drum systems. Both systems use friction or resistance to stop the vehicle. Based on the brake system your car has, it may experience different problems that may lead to your car pulling to the left or right when brakes are applied.

There are many reasons why this happens. Let’s have a look at some of the causes that may lead to a car pulling to the left or right.

Uneven tire pressure

When there is a pressure difference between one tire and the other, this can cause the car to brake while moving to the right or left. Low pressure on one side changes the height and relative speed of the tire, changing the alignment of the car.

Stuck caliper

When one of the brake calipers is stuck the car will pull on one side when braking. The same issue can also be experienced when one is not braking.

Worn suspension parts

Suspension parts get worn out over time, this can be the cause of this kind of problem as well. The problems can be in the joints, springs of any other part. Due to the stiffness of the suspension parts which cause the vehicle to pull to one side of the road.

Your Tires need an alignment

If your right and left tires are not working together and pointing exactly straight down the road the will need to be aligned.  If they are left out of alignment you will notice the car pulling to the side and your tires will wear down faster.


It is advisable that one should have a mechanic come over and check the vehicle’s braking system to make sure everything is working correctly.

One of the biggest difficulties car owners face is knowing how to effectively maintain and care for their automotive. There are certain sings that if you start experiencing then you will need to take immediate action so that you can save the extra cost for replacing the damaged parts. Have you wondered when you should change the oil in your car. Here are some hints from http://drivethrucarcare.com/ to help you know that it is time.

Loud noise from the engine

When your oil is still fresh, there will be a thin shield created between the parts of the engine which reduces the friction. This ensures the motor is silent and works smoothly as you drive. When the engine gets too hot, the lubricants will be broken down. This will increase the sound in the engine system. This indicates that it is time for an oil change.

Dirty And Dark Oil

Oil color is a good indicator to show you whether you need to change the oil or not. As a beginner, you should know that the fresh oil always has an amber color. But when you discover the color is changing to black and greasy, then you’ll know that more dirt and particles have built up in the engine and have combined with your fresh oil. It’s time for you to do the change. For consistency, ensure you check the color on the monthly basis.

Observe Your Oil Change Light

Cars are designed with the ability to show you when the oil should be changed. The light in the dashboard will be on whenever there is a reduction in the level of oil in your car system. At this point, a dipstick can help you to know the exact level. If it’s too low, it is time for an oil change.

Smoke from your exhaust

During the cold weather conditions, you should expect to see vapor comes out of your exhaust pipe. But if you see smoke, then you should check the level of your smoke. There may be a problem in your tank, perhaps there is an oil leakage or some part of the engine isn’t working normally. If you discover it’s the problem with your oil, then this indicates it is time for an oil change.

There are many instances where air from the AC comes out cool but not cold. This is a clear indication that the Air conditioner system has a problem which should be addressed immediately to avoid stuffiness inside the car. When the air conditioner is working correctly the fan will draw air over the evaporator coils and recycled back into the car.

If air conditioning is set to max cold and the fans on high yet the car blows only moderately cool air. This is a clear indication that the AC system is not working properly.  If the car conditioning system does not work properly the problem could be with the compressor or the AC could be low on refrigerant. When air from your AC is blowing air that is not cold while the environment around is warm. This means that you are either experiencing clogged filter, cooling fan problem or radiator trouble. Auto Repair Rancho Cucamonga suggests the following steps to troubleshoot the problem:

Checking the problem

Checking the cool but not cold problem

For cases of cool but not cold, check the condenser, cooling fans and compressor and ensure that they are running when the air conditioning system is running. You should also check for any blockage that could restrict air from flowing. This can be caused by leaves, bugs not forgetting dirt.

Checking the compressor

Checking the compressor is the easiest step, to begin with. First ensure the engine is running and the AC is on maximum cool, also ensure the clutch is interacting with the compressor. If the clutch is not working well with the compressor use the voltmeter to check for voltage getting into the compressor. If there is power from the clutch the problem could be with the compressor.

Checking for leaks

Leaks are common in most AC systems. When the pressure is low then there are leaks in the system. Using the UV AC detection took kit it is easy to detect the leaks. Start with the hose manifold on the compressor. Then to the Schrader Valve all the way to the evaporator.

A properly working AC will keep your car fresh at all times. If the AC is not working properly ensure the mechanic for further inspection. Ensure to keep the AC system working properly at all times for fresh cold air inside the car.

Have you ever left your truck parked and when you returned to the parking lot, come across some fluid near your truck? First things first, do not panic, and let’s start the troubleshooting to resolve this issue

Where is it coming from?

The most important of all is to determine whether this fluid is really coming from your truck or not; Sure, it may be right next to your truck, but this doesn’t necessarily mean that it’s from your own truck, it might have been there a long time already, from another vehicle that was parked in a nearby spot before.

Is it Clear?  It might be Water.

There is also a possibility that the leak is A/C (air conditioning) fluid, especially if you’ve been running your A/C. The A/C fluid naturally does not have any color so if it looks like water, it is a normal evaporative process from the A/C and nothing to worry about.

Green Fluid

However, if the fluid is green and is indeed leaking from your truck, there is a very good chance that it could be antifreeze fluid. In most cases, these leaks come from the radiator, water pump, or any other hoses or gaskets that are not secured properly, or have worn out.

What Do I Do Now?

And as for repairing, the cost can greatly vary, being dependent on which part is specifically causing the leak. If the only thing to be repaired is the radiator’s hose, it will be quick, affordable and easy, ranging from $35 to $65 for the entire service. If the leaking problem is being caused by blown gaskets, it will be a bit more expensive and time consuming, due to these specific parts themselves costing around $75, plus the great deal of labor it will take. Finally, if the issue is the radiator itself, replacing it entirely for a new one will be around $300 or more. Anyway, it’s absolutely essential to not delay in repairing the leaking problem, since these fluids keep the engine functioning properly.

You may be wondering what is causing your BMW to stall when you take your feet off your gas pedal. There are quite a few possibilities that could cause this issue. You can troubleshoot BMW Service stall problems by ruling out a few possibilities.

Vacuum Leak

You should first check for a possible vacuum leak. The rubber hoses at the throttle body or intake plenum could have been disconnected. These hoses get brittle with age and don’t hold tight.

After you lift the hood, listen to the hissing noise. A visual inspection of hoses could also help. If you find any hoses dangling without being connected, you need to find where it connects and fix it.

Air Flow Sensor

If you don’t find any problem with a vacuum leak, you should check the mass airflow sensor. To troubleshoot airflow sensor, you should unplug MAF sensor and try to drive the car. With the MAF plug disconnected, the PCM has to depend on preprogrammed parameters.

If you find the car running better with MAF unplugged, you can clean the MAF sensor to eliminate grime and dust causing erroneous data. If it doesn’t solve the issue you may have to replace the MAF sensor.

Check Electrical Connections

Sometimes electronic connections get dislodged. Make sure that the electrical connections to the ISC are intact.

Most of the times, you could fix the problem by just looking at the above possibilities. If you still find you are not able to locate the problem, you can take the car for service. However, there is nothing to panic since it is a minor issue which doesn’t take much of your time and money. If you notice this issue, don’t wait for it to get worse.  Troubleshoot it as soon as possible and it could save you trouble and further deterioration of vehicle.
