Ignition Timing

NOTE: Verify that increasing engine speed advances ignition timing.

Ensure transmission is in Neutral or Park. Set parking brake. Inspect crankshaft pulley timing mark and timing mark indicator on timing belt cover. Clean marks as required. Start engine and allow it to reach normal operating temperature. Turn all accessories off. Attach timing light to No. 1 spark plug wire. Ensure idle speed is correct. See IDLE SPEED SPECIFICATIONS table under IDLE SPEED & MIXTURE.
CAUTION: Driving with jumper wire installed in test connector will damage catalytic converter.
Using a fused jumper wire, connect terminals "D" (ground) and "E" (test switch) of test connector. See Fig 1 . Aim timing light at timing cover timing marks. If ignition timing is not within specification, loosen distributor hold-down bolt and rotate distributor to obtain correct ignition timing. See IGNITION TIMING table. Tighten distributor hold-down bolt and recheck ignition timing.
