Ignition Timing

NOTE: Before adjusting ignition timing, warm engine to normal operating temperature. Turn off all accessories. Place transmission in Neutral (M/T) or Park (A/T). Ensure idle speed is correct. See IDLE SPEED under IDLE SPEED & MIXTURE. If ignition timing is not within specification, loosen distributor or crankshaft position sensor lock bolt. Rotate distributor or crankshaft position sensor until timing marks are aligned. Tighten lock bolt.

Engine is equipped with an electronic distributorless ignition system. Base (initial) timing is preset at 8-12 degrees BTDC and is not adjustable.
