Ignition Timing: Adjustments

Ignition timing is electronically controlled by the Powertrain Control Module (PCM) and is NOT adjustable.

Adjusting the distributor will NOT change the ignition timing. It will change the fuel system synchronization and can cause driveability complaints. Refer to TSB's if the vehicle exhibits surging, bucking, intermittent missing or other driveability symptoms.

If you are installing the distributor for the first time (I.E. during and engine rebuild), refer to Distributor/Service and Repair for distributor installation procedures.
