You will need to make sure the CMP sensor wires are not out of position and near any high voltage wires or coils. If the problem continues then remove the sensor again and check the reluctor on the cam for...

Both choices are very high end cars and will have high end service and repair costs. Generally though, I find the costs on the Porsche to be higher. Either car will likely be displaying warning lights and needing unscheduled repairs...

This may be a sign of low transmission fluid or a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears. Every time a gear change is required, the car's computer activates a transmission...

You may not have an O2 sensor problem at all. I would need to know the codes and problems you are having to give a complete diagnosis. I would suspect you are getting codes like P0171 or P0174. These are...

Hello. The numbers you have provided did not yield any results through my search. If the part numbers are different, and the ends are physically different, then they may very well be different coils or it may just be an...

It sounds like you may have a weak battery, a failing voltage regulator or failing alternator. As you may know, the alternator charges the battery while the engine runs by generating amperage and recharging the battery while the engine turns...

It sounds like you may have a brake light bulb that needs to be replaced. Inside a brakelight bulb there are two different filaments - one that i illuminated when the regular taillights are on and one that is illuminated...

Hello, thank you for writing in. Two aspects about the issue lead me to believe the previous technician is correct. To start, the compressor is the only component that will effect the engine, as it is the part connected to...

While I don't wish to cast stones, it doesn't sound like you have been getting very good advice. A car that doesn't start at all is usually the easiest kind of problem to diagnose. It's the cars that only fail...

A possibility with the A/C system is a fault in the evaporator that causes internal and/or external icing. The resulting high head pressure causes the control circuitry to "throttle" the compressor, hence the ECON mode. Check for a blocked air...

Hi Paul. Thanks for contacting us today. In many US states, there are regulations about the proper disposal of mechanical parts that are potentially hazardous. The catalytic converter is one of these parts. So, I would agree with the mechanic...

A car basically needs 3 things to run. Air, fuel, and spark. If one of those is missing the engine will not work. Since we know you are driving air shouldn't be the problem unless you have something clogging your...

A slight hissing sound that may increase in frequency as the vehicle speed increases may be from the brake lining wear indicator. The noise can start as a slight hiss or scratching noise and turn into a squeal as the...

It is not advisable to mix coolant types. Over time, a chemical reaction happens between them. This can cause corrosion issues, and the mixture can begin to gel, clogging small coolant passages in components such as the radiator, intake manifold,...

Hi Douglas. Thanks for contacting us today. It's is quite possible that the root source of this issue is a PCV valve or other vacuum leak. Knowing the OBD-II trouble code that is triggering the warning light would be a...

Trouble codes do not represent a diagnostic and consequently parts should not be replaced merely because they are listed in a code description. Trouble codes are best considered indicators or clues as to the general area of the problem. If...

It sounds like you may have a faulty MAP sensor. The Manifold Absolute Pressure (MAP) sensor senses engine load and generates a signal that is proportional to the amount of vacuum in the intake manifold. The engine computer then uses...
