Cylinder #1 Misfire. 2007 JKU automatic. This started in December, was intermittent at first now is quite regular, my local guy and two dealerships are stumped. Things replaced:
Plugs, wires, coil, injector, crank PS, cam PS, harmonic balancer, idler pulley, combustion chamber cleaner 3x, head pulled by dealer, pulled apart by machine shop, reinstalled, reinstalled factory TB, PCM replaced. That's all I can think of for now. When I had the head pulled it ran great for a couple weeks then started back up, same with the PCM. It is an obvious miss, engine runs rough, you can hear it in the exhaust, only lasts less than 30 seconds, most times 10 seconds or so.
Any ideas?
Thanks.
