You should not need to ever replace a PCM unless you put it under water. Diagnose your vehicle or have someone that knows cars do it.

I think you would need a reflash.

thanks for the help,i did have the pcm diagnosed as the probable problem. I dont see why one mechanic would find it hard to believe that a 20 year old computer would malfunction. In my experience, anything can break.

They do fail, but usually there is something that caused it, over or under voltage is a biggie, then there are those that just plain fail, who knows the reason. Thanks for the points.
