Idle Speed

NOTE: Idle speed is controlled by Powertrain Control Module (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 Diagnostic Trouble Codes (DTCs). See SELF-DIAGNOSTICS - EEC-V article. If no DTCs exist, go to TROUBLE SHOOTING - NO CODES - EEC-V article.
