just took my car to the dealer for a mysterious idle and stumbling during acceleration.

They hook up the pcm and it reads a 4 cylinder escort....

gonna need to get a new pcm before anything can be diagnosed i guess. im gonna look for one at a junkyard. is 1994-1997 the same pcm? i think for some reason that 1998 is different. then obviously 99 on is different.

do i need a 96 gt pcm or what are the years that i could use?

Thanks
