Ignition System: Distributor

The 2.8L (VIN W) engine is equipped with the DIS ignition system. This system uses a 3-coil module along with a magnetic sensor to determine crankshaft position in place of a distributor.

The 3.0L MPFI (VIN L) and 3.8L (VIN C, 3 and 7) engines are equipped with C3I ignition. The system uses a 3-coil module and Hall-Effect sensors to determine crankshaft and camshaft position in place of a distributor. Models that use a distributor, are equipped with High Energy Ignition (HEI) system with Electronic Spark Timing (EST).
