Hello I believe you are referring to the variable valve timing or camshaft position actuator/solenoid, which varies the camshaft timing relative to the crankshaft position. This feature enhances engine performance, mileage, and lowers emissions. If you are able to get...

Hi there. Any solution will help clean out the fuel system. I recommend getting Sea Foam and putting the whole bottle in the fuel tank and fueling up the tank. This solution will remove all water in the fuel, debris...

Hi, thanks for writing in. If you have coolant in the engine oil showing on the oil cap, then you likely have a blown head gasket. The oil in the coolant is most likely from the blown head gasket getting...

Your ECU would have to be programmed. Although it is possible nowadays for consumers to download the software from the OEM for a fee, you need an interface cable and knowledge of the programming steps. Once you add up the...

You should have the computer tested for codes and then have the steering checked to see if there is a steering or engine issue with idle since it is normal for the engine to increase the idle when it senses...

Hi there. Unfortunately, I think Jay is correct here. Usually when you see air bubbles in the filter, it's due to a pick-up issue or debris in the fuel. If the gas tank is the original one from 1980, it...

Hello. From what you describe it would appear likely that the backfiring and performance issues are a result of the fuel problem. A rich fuel mixture can be caused by a wide variety of issues. A few things I would...

To me, they are over-engineered, gigantic money pits. They cost a fortune to fix as they age. That's the truth. If you really like Audi's and want to buy one, then I would opt to lease it. If you...

From the information provided on your Chevy Camero, it appears that you need to adjust the Throttle Valve (TV) cable. This TV cable on your Chevy Camaro controls hydraulic line pressure, the shift points, the shift feel and throttle downshifts....

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...

Your car has a small purge valve that controls the venting of fumes from the fuel tank as these fumes build up inside, particularly when you are refueling the car with gas. The EVAP system prevents fuel vapors from the...

Hi there. I would check to be sure the engine is getting fuel, air, and spark. If the Check Engine Light is on, I would recommend having it hooked up to a scanning tool to see what trouble codes have...

Hi there. If there is fuel and the engine will not start up when it is at operating temperature, then either the crankshaft position sensor is getting hot and not making a connection or the coolant temperature sensor is malfunctioning...

Hi, thanks for writing in. Depending on the severity of the surface area of the tire that has been patched and the location of the patch, this could be fine, but is not recommended. Sidewall patches are particularly vulnerable to...

Hello. If this occurs right after the oil change it is because the vehicle was put up in the air to service it. When this occurs the bushings and shocks over extend, which ends up putting them in the wrong...

Hi there - there are several possible cause for over-retarded cam timing. The VCT solenoid could cause this, but a failed cam phaser, worn timing chain guide, stretched timing chain or simply low oil pressure can also cause this problem...

Hello. I would need to know what services have been done on the vehicle to know what needs to be done. A typical 30,000 mile service on this vehicle includes a few filter changes and an oil change. It also...
