Ignition Timing

NOTE: Perform all adjustments with engine at normal operating temperature, cooling fan and accessories off, transmission in Park or Neutral, and front wheels in straight-ahead position. Set curb idle speed to specification. See IDLE SPEED SPECIFICATIONS table under IDLE SPEED & MIXTURE.

Locate ignition timing adjustment connector. See IGNITION TIMING ADJUSTMENT CONNECTOR LOCATION table. Connect jumper wire between ignition timing adjustment connector and ground. Check ignition basic timing.

If ignition basic timing is not within specification, loosen distributor (or crank angle sensor on engines with dual coil assembly) and rotate to adjust timing if necessary. See IGNITION TIMING SPECIFICATIONS table. Remove jumper wire from ignition timing adjustment connector.
