Idle Speed

NOTE: Idle speed is controlled by Powertrain Control Module (PCM) and is not adjustable. Idle speed specifications are for reference purposes only. If engine idle concerns are present, check for contaminated fuel, vacuum leaks and incorrect ignition timing. Ensure throttle bore, EGR system and PCV system are clean. If these are okay, check PCM for Diagnostic Trouble Codes (DTCs). See appropriate article:

For SOHC engines, see TESTS W/CODES .
For DOHC engines, see TESTS W/CODES .

If no DTCs exist, go to TESTS W/O CODES .
