Ignition Timing
- Ensure engine is at operating temperature, all accessories are off, and transmission is in Park or Neutral. Set parking brake. Ensure idle speed is correct.
- Connect timing light to No. 1 spark plug wire. Remove shorting bar from double-wire Spark Output (SPOUT) connector. Shorting bar is located near distributor, in wiring harness to Ignition Control Module (ICM). Start engine. Check base ignition timing. See BASE IGNITION TIMING
table.
- If timing is not correct, loosen distributor hold-down bolt. Adjust timing as necessary. Turn engine off. Install shorting bar in double-wire SPOUT connector. Start engine. Check computed ignition timing. Computed ignition timing should be advanced beyond base timing.
