Ignition Timing Adjustment
1. Refer to the tune-up label located in the engine compartment. Follow all instructions on the label.2. With ignition OFF, connect the pick-up lead of timing light to the number one spark plug. Do Not pierce the wire or attempt to insert a wire between the boot and wire. Connect the timing light according the the manufacturer's instructions.
3. Start the engine, and aim the timing light at the timing mark. The line on the pulley will line up at the timing mark. If a change is necessary, loosen the distributor hold-down clamp nut with special tool J-29791 (or equivalent) at the base of the distributor. While observing the mark with the timing light, slightly rotate the distributor until the line indicates the correct timing. Tighten the hold-down bolt (or nut) and re-check the timing.
4. Turn off the engine and remove the timing light. Reconnect the number one spark plug wire, if removed.
NOTE: Use "Fixed Spark" mode to check ignition timing. Refer to Ignition System / Testing Procedures / "Fixed Spark" Mode.
