Default intermittant misfires

Hello, new to forum so please bear with any mistakes. I have a 2005 2.4 auto. frequently the engine light comes on and car starts missing bad. will barely pull itself. I can turn off ignition switch for a few seconds and start it up and light is off and runs ok until next event which may be 30 seconds or 30 minutes. while light is on L get a 2302 code. after startup light is off and code is gone it does not store in pcm.put on new pcm,coil, plugs and wires, camshaft sensor. Does anyone know which sensors light the 2302 code? thanks for any help at all bobrat

bobrat, there must be more to the story your telling. Have you done a through diagnostic of the problem to show that you need a new PCM? Has the coil driver circuit been checked? That's the wires leading from the PCM to the coil but first you needed to check the spark at the coil to see if the fault had come from there. Coils on these car very rarely fail. Were they (PCM & coil) new and was the PCM flashed to your car?
