Ignition Timing

  1. Turn ignition off. Place transmission in Park or Neutral. Turn off all electrical loads. Disconnect in-line Spark Output (SPOUT) connector. Start engine (DO NOT use a remote starter).
  2. Start engine and warm to normal operating temperature. With engine at idle speed, check initial (base) timing.
  3. Turn ignition off. Reconnect IAC solenoid or single-wire SPOUT connector. Check ignition timing advance to verify distributor is advancing beyond initial setting. Disconnect test equipment.
    NOTE: Electronic Ignition (EI) low data rate and high data rate systems cannot be adjusted. Check Camshaft Driven (CMP) Hall sensor, synchronizer sensor orientation, timing belt/chain, etc.
  4. If timing is not within 2 degrees of specification on emission label, adjust timing as necessary. If unable to adjust timing to specification, check engine mechanical condition (distributor orientation, timing belt/chain, etc.).
