Had a buddy that has a 98 SVT. He has been having a miss problem since he got the car. He has replaced everything! I have him another 98 SVT PCM to swap in. HIs dad owns a Ford dealer and the techs said he needs some specific codes. It's just not a direct swap. More has to be done to the car. There are a ton of other little modules that have to be messed with. He gave up on it after running in the same situation as you. It's just not some plug and play swaping in another PCM is my understanding. Might want to contact Dom on fordcontour.org as he says he swapped an SVT PCM into a non SVT car successfully.
