BASE TIMING The distributor ignition system has no provision for timing adjustment. The base timing is preset when the engine is manufactured and no adjustment is possible. The distributor may need adjusting to prevent crossfire. Refer to Camshaft Retard Offset Adjustment See: Ignition Timing > Adjustments > Camshaft Retard Offset Adjustment Ignition timing can only be changed by reprogramming the PCM using Techline Information System 2000 (TIS 2000) PC, and the Tech 2 scan tool. Please contact your dealer for necessary updates and procedures. timing marks for the timing chain are below, you will want to use a compression gauge / compression whistle to get to TDC first .
