I know I have a miss on 7 cylinder. I have verified that the plug, wire, coil and coil subharness are all good. I even swapped everyting to 3 cylinder and no change. I put a noid light to the 7 injector plug and it is working properly as well. The only thing I can come up with on this is that either the wire going to the coil from the PCM is bad, or the injector itself is physically clogged. But honeslty would a miss on one of the 8 cylinders cause the transmission to go into "limp mode"??
