Idle Speed
NOTE:
Idle speed is controlled by PCM and is not adjustable. Idle speed specifications are for reference 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 DTCs. See SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV
article. If no DTCs exist, see TROUBLE SHOOTING - NO CODES - EEC-V - GASOLINE & NGV
article.
