The cycling of the AC compressor is normal as the compressor cycles on and off. You may also hear a bit of a change in the exhaust as this happens. The computer will automatically compensate for the additional load the...

From what you describe it sounds like you have front wheel bearings that are noisey. They do not have to be loose to be noisey. Have the vehicle lifted and ran in drive to see if the noise can be...

Your clutch master cylinder is probably out of fluid. Topping it off probably won't do the trick because it now has air in the system that needs to be bled out. You might be able to get some activity out...

The serpentine belt (aka drive belt) (https://www.yourmechanic.com/services/serpentine-drive-belt-replacement), is the belt that drives the accessories on the front of the engine. It drives the alternator, water pump, power steering pump, air conditioning compressor, and any other belt driven accessories. This is...

Hi there: It's very difficult to tell you where to start if we don't know what type of troubles or symptoms you're experiencing. A professional mechanic typically will download OBD-II trouble codes first, then test drive or communicate with the...

Hello - I suspect the answer to this question revolves around whether you are making other modifications to the engine, and how often you drive with boost pressure near the limit. This device will offer more precise control for managing...

Hello, thanks for writing in. If this occurs only under this high load condition then most of the time it is caused by a boost leak. I usually suspect that the intercooler has a crack as that will cause this...
