Ignition Control Module (Protege)
WARNING: This page is about a different car, the 1996 Mazda Protege. However, it is still accessible from the selected car via links, so may be relevant.
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.
