1. Turn all accessories off. Set parking brake, and block wheels. Connect timing light to engine. Disconnect single in-line Spark Output (SPOUT) connector (Yellow/Light Green wire) near Ignition Control Module (ICM) at distributor.
2. Start engine and warm to normal operating temperature. Place transmission in Park (A/T) or Neutral (M/T). With engine at idle RPM, check ignition timing. Turn engine off. Reconnect in-line SPOUT connector. Check computed ignition timing. Computed ignition timing should be advanced beyond base timing.
