Ignition Control Module
Check ignition coil, PCM and high tension lead connections. Check secondary coil winding and high tension lead resistance. Measure voltage at appropriate PCM terminals. See PCM TERMINAL IDENTIFICATION table. If all measurements are within specification, and misfire still occurs, replace distributor or ignition coil.
