V6 Ignition Timing: M30
- Start engine, and warm it to normal operating temperature (needle is in middle of coolant gauge). Operate engine for 2 minutes at 2000 RPM. Perform self-diagnostic procedure, and check for smooth engine operation. See G - TESTS W/ CODES article in the ENGINE PERFORMANCE Section.
- Increase engine speed to 2000 RPM, 2 or 3 times, and then allow engine to return to idle. Connect timing light to cylinder No. 1 spark plug cable. Check ignition timing. See IGNITION TIMING table. If ignition timing is incorrect, loosen crank angle sensor mounting bolts. Adjust timing by turning sensor. With ignition timing correctly set, check idle speed and mixture. See IDLE SPEED & MIXTURE.
