The ignition timing is not adjustable, but the ignition base timing can be checked by performing the following:
- Before servicing the vehicle, refer to the precautions in the beginning of this section.
- Connect a PGM tester (scan tool) to the data link connector.
- Connect a timing light to the No. 1 ignition cable.
- Start the engine and allow it to warm up until the electric fan comes on.
- Be sure to turn off all accessories.
- Verify that the idle speed is set to specification.
- Point the light at the timing belt cover near the crankshaft pulley and read the timing. Correct timing is 10-14° Before Top Dead Center (BTDC) for both automatic and manual transmissions. If necessary, loosen the distributor hold-down bolt and rotate the distributor slightly to adjust the timing. Turn it counterclockwise to advance and clockwise to retard the timing.
- Tighten the hold-down bolt to 16 ft. lbs. (22 Nm). Recheck the timing after the bolt is tight to confirm the correct timing.
Disconnect the PGM tester.
