If you experience cold starting problems, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steadily and run when the accelerator pedal is not pressed.
The engine may have a higher that normal idle at times. After cold start with an automatic transmission and when the clutch is depressed with a manual transmission. Our technicians tell us updated powertrain control module (PCM) software is available to address this concern.
Bogging, hesitation or stalling may be experienced during moderate to heavy acceleration. This can be caused by a failing of many sensors or modules in the fuel injection system. It is recommended to have an experienced shop perform diagnosis to find the root of the problem.
If a noise from the rear end is heard when going around turns or after driving at highway speed for an extended period, this could be caused by a failing deferential clutch kit. An updated differential clutch kit available.
