Ignition System: Description and Operation

The Distributor Ignition (DI) system features a camshaft driven distributor which uses no centrifugal weights or vacuum advance.

Initial timing adjustments are not required unless the distributor has been moved from its factory setting or removed from the engine.

The DI system features computer controlled dwell ignition. The Powertrain Control Module (PCM) controls dwell times for the ignition system.
