So I bought a mustang GT with bad tags and issues... later I found out the PATs system was messed up and it was swapped from an automatic trans to a manual. When I purchased it it was running horrible and was spitting flames from the exhaust. So I fixed the PATs system, for the key ring reader was broken. Swapped the PCM to a 1996 Mustang GT Automatic PCM. It is really difficult to start up and you need to use brake cleaner and once it start it has automatic transmission codes, but the PATs system proves out fine. So today I went to the junkyard and got a 1998 Mustang GT Manual PCM and now the PATs starts flashing like crazy as if it's broken again. I did some research, and was reading that the 1998 PCM has the PATs in the PCM itself or something like that. Can I try to reprogram the single key that I have for the GT and see if the PATs system works and will start the car? Currently the car just cranks and will sputter with brake cleaner with PATs flashing a lot.
