V6 & V8 Ignition Timing
- Connect tachometer to check connector. Check connector is located on right rear corner of engine compartment, near automatic transmission dipstick. Remove No. 1 or No. 6 ignition coil. Connect No. 1 or No. 6 ignition coil and No. 1 or No. 6 spark plug with a high tension wire. Using insulating tape, enlarge coil end of high tension wire to fit tightly into coil. Connect conductive timing light to high tension wire. Start and warm engine to normal operating temperature.
- Operate engine at 2000 RPM for 2 minutes. Perform self-diagnostic procedure, and check for smooth engine operation. See G - TESTS W/ CODES article. Snap throttle to 2000-3000 RPM, 2 or 3 times, then allow engine to return to idle.
- Check ignition timing. See IGNITION TIMING table. If ignition timing is incorrect, loosen crank angle sensor mounting bolts. Adjust timing by turning crank angle sensor. With ignition timing correctly set, check idle speed and mixture. See V6 & V8 IDLE SPEED
and also IDLE MIXTURE
. Reinstall removed components.
