Ignition Timing: Adjustments

The base timing is preset when the engine is manufactured, no adjustment is possible.* Timing advance and retard are accomplished through the powertrain control module (PCM) with ignition control (IC) and knock sensor (KS) systems.


*Ignition timing can be changed by reprogramming the PCM using Techline Information System 2000 (TIS 2000) PC, and the Tech 2 scan tool.
