[QUOTE="christopher.d.carr, post: 420867, member: 17446"] Hello to all JK folks, I have an 07 JK named Petunia (its my wifes, and I did not name her, but we love her just the same.) Anyway, shes got 114k+ and we replaced a cracked header with shorty stainless heads. Now theres a misfire, which started on Cyl 4, and I just replaced it, but theres still a rough idle. Anyone of the shadetree mechanics know what all I need to do next to make her a superstar? I am thinking she might need a new ignition. p0304 was the only code and it cleared after the plug wire was replaced. I know from experience that the most experience and know-how is on these forums. I had an explorer, f150 and f250 that the forum guys blew my local mechanic's mind. I need expert advice, she's going to "get the buisness" with upgrades eventually. Thanks for the help!
