Ignition System: Distributor

The 2.0L (VIN 1) and 2.5L (VIN R and U) engines use a Direct Ignition System (DIS). Ignition timing information is taken from a crankshaft mounted timing disc by a magnetic sensor.

The 2.3L (VIN A and D) engines use the Integrated Direct Ignition (IDI) system and does not use the conventional distributor and coil. The system consists of 2 separate ignition coils, an ignition module and a secondary conductor housing mounted to the aluminum cover plate. This system utilizes the EST (Electronic Spark Timing) signal from the ECM to control spark timing.

The 2.0L (VIN K and M) engines are equipped with the Delco-Remy High Energy Ignition system with Electronic Spark Timing HEI-EST). The HEI-EST distributor is not equipped with centrifugal or vacuum advance mechanisms since all advance is controlled by the Electronic Control Module (ECM). See Figure -Figure .
