Idle Speed

NOTE: Idle speed is controlled by PCM and is not adjustable. Slight fluctuations in idle speed are considered normal. Start and run engine for at least 7 minutes to establish PCM control of idle.
NOTE: Incorrect idle speeds are normally caused by dirty throttle plate or vacuum leaks. Ensure all vacuum components are functioning properly.

Idle speed is PCM-controlled. Resetting of IAC valve pintle is the only adjustment that can be performed. To reset IAC valve pintle position, depress accelerator pedal slightly. Start engine and release accelerator pedal. Run engine for 5 seconds. Turn engine off for 10 seconds. Restart engine and check for proper idle operation.
