Ignition Timing

Adjust ignition timing with engine at normal operating temperature. Disconnect timing connector, which is a tan/black single wire sealed connector. The timing connector is located below the heater case in the passenger compartment. Connect a suitable timing light to No. 1 spark plug wire, as per timing light manufacturer's instructions, then check ignition timing. Adjust ignition timing as necessary.
