Stop leak in the cooling system is likely to cause more problems than it will solve. Modern cooling systems are much more finely drawn and have far smaller passages than older cars, and stop leak will jam things up. I...

The knocking noise is usually an indication of an internal failure of some kind. This may be related to many different things, however the reduced engine power mode usually indicates that the computer has detected something wrong and is attempting...

There are a few components behind the dashboard that may cause a humming noise as there are doors that open and close to direct air flow, motors that control them and the fan or blower motor which may make a...

Hi there. This is typically caused by warped rotors. When the rotors are warped, the steering wheel will shake when applying the brakes. This is a common issue. I usually measure the rotors to see if they are good, but...

You will need to see if you have lost spark to the spark plugs after the engine dies. If it did then you most likely have a bad distributor assembly behind the water pump. Make sure you replace the spark...

Hi there. Although our mobile mechanics can typically replace steering / suspension components, we are not able to complete suspension alignments. Since it's highly recommended to have this service completed at the same location and before driving the vehicle, I...

It sounds like you may have a dirty or failing idle air control valve. The idle air control valve monitors the air intake as it is mixed with fuel prior to being injected into the engine at low speeds and...

Hey there. This maybe related to many different transmission components such as a speed sensors, the transmission control solenoid or the module itself. The transmission control solenoid controls the flow of transmission fluid inside the transmission. Every time a...

If the coolant level is so low that the temperature sensor that is threaded into the cooling passageways does not contact any coolant, you could get a false reading on the dash temperature gauge. In addition, it is possible that...

Firstly, I would recommend checking the water pump for leaks and testing it to make sure it is flowing correctly. Also, as a means to eliminate another possible problem, while you are at it, I would check the coolant fan...

Hello. From what you describe it would appear that your vehicle may be experiencing two separate issues. If your wiper motor is not functioning despite it being replaced then it may be possible that there is some sort of wiring...

Hi there. There are 3 different mounts used for your vehicle. There is a left engine mount and a right engine mount and a transmission mount. Both the engine mounts are the same and the transmission mount is flat and...

If the engine swap was for a "complete", 100% assembled engine, the gaskets (oil pan and valve cover) are already in place. If the engine swap was a complete rebuilt (re-manufactured) engine, you needn't worry about leaks at the oil...

I would not recommend driving your truck under these conditions to prevent transmission damage. My first recommendation would be to have your transmission system inspected by an automotive service professional to locate the source of the leak. Possible leak sources...

Based on these fault codes, it sounds like you have an oxygen sensor that as failed and it will need to be replaced. The trouble codes will also have to be cleared after the sensor is replaced to see if...

Hi there - great diagnostic work! At this point, having identified which circuit is causing the drain, you will need a wiring diagram that identifies what other devices are on this circuit (clock, underhood light maybe?), and could be drawing...

Hi there. This video is actually pretty good on learning how to correctly replace the throttle body on your vehicle. This is another good video to learn from. It is possible that your fuel injectors are still clogged with debris...

Hello. From what you are describing, it sounds like the mass airflow (MAF) sensor is not working properly. The mass airflow (MAF) sensor helps to regulate the air/fuel mixture and the idle of the car. When the mass airflow...

If the car does move (in reverse) then the wheel is not locked. There may be an issue with the transmission and/or the shift linkage. To resolve this, please request a transmission shift diagnostic. If you request that service, the...

Hi there. I would not recommend bypassing any electrical connections that are used in conjunction with any security system. It typically creates more problems than helps. You might want to consult with a local car audio / alarm installation company...

Hi there. Typically when an EVAP system component fails or is damaged, it will cause performance problems, issues filling the fuel tank or other symptoms with the operation of the vehicle. If you are not having these problems, it's likely...

Hi there. What you are describing is typically an indication a broken or cracked exhaust manifold or exhaust pipe downstream. The exhaust systems on cars, trucks and SUV's are finely tuned to expel exhaust gases from the combustion chamber and...

Hi there. It is very rare for an ECU to fail completely, unless something dramatic happens to cause this to occur; such as attaching battery cables backwards or flood damage / excessive exposure to water. Unfortunately, the best way to...

It's possible that a leaking injector or injector o-ring could be making your Pontiac smell like gas. These items could also cause driveability issues, such as the ones you describe.There are other potential causes as well though, such as a...

First thing you want to do is jack the car up in the air, pull on the wheels and see if anything's worn out. A lot of times the tie rods are worn out and they wobble so change that....
