Message I have a 1990 tt. Cylinder number 2 has been misfiring off and on for a week now. I replaced the spark plug because it was done but misfire still persists. I ohmed the injector the other day when It was running rough and I got no reading. Today it was running with a very slight misfire and I ohmed the injector to get 12.6 the wire connector for the coil pack #2 also works sometimes(mainly when the injector is working). The ptu is new so I dont see why I am not getting any power to the coil packs. Could my ptu and injector both be going out at the same time or can this be related to something else?
