    Yes, I also had the misfire counter on Jscan running. It has close to 200 misfires on 4. I don't think it fired once

    Cylinder 4 misfire. Please help!

    Only code is cylinder 4 misfire. The pins all look fine. I have not checked the resistance. I'm terrible with wiring/electrical work but I did order new pigtails for the injector and coil.

    Cylinder 4 misfire. Please help!

    I have a 2012 Jeep Wrangler with only 70k on it with a cylinder 4 misfire. I changed everything including a new cylinder head. Prior to replacing the cylinder head I was getting misfires from cylinders 2, 4, and 6. Any suggestions are much appreciated! Items replaced are catalytic converters...
