I recently bought a 1996 GT. It had been sitting for 4 years in a guys backyard with a broken transmission. Got transmission fixed picked car up and it was misfiring. Ran computer test came back p351 bad coil pack not firing on cylinders I and 6.. Bought brand new Ford motorsport wires new coil packs, new plugs. Everything pretty much brand new. With no other options I ordered new PCM. Put it in and the code was same only now it's missing on 4 & 7. So 1 & 6 are firing with new PCM but 4&7...

Misfiring Please help
