I drive an '02 Mustang and the Ford dealer told me that the PCM and the MAF were bad. Is there anywhere I can get a pre-programmed PCM and if i can is it something I can do myself? Im not a mechanic but I can pretty well find my way around an engine.
You can get a preprogrammed PCM at a junkyard, but its programming will prevent it from working with your car. It would still have to be reprogrammed by someone with a WDS or other dealer-level scantool.
What's the symptom that made you take it to the dealer?
