2002 dodge caravan i had a minor accident and needed the pcm replaced .everything was fine and then it starting running rough and sometimes the radio and windows wouldn't work and then they would .I took it to my mechanic and he said the pcm wires fused together and that I needed to replace the pcm so I did .found out the pcm I replaced it with after the accident was for a 2003 dodge caravan. So I ordered the preprogrammed pcm installed it and it starts but the check engine light is on .sent it back got another one and the same thing. Something about missfire code but it starts up fine.
