[QUOTE="Sigp320vtac1, post: 461256, member: 25593"] Okay I’m new here so sorry if posted in incorrect place. I have a 2008 jku that threw a 02 sensor code and a Cat code also was throwing a misfire code. I knew my exhaust was bad so I ordered all new cats and pipe all the way back including muffler. It’s all new. I also replaced all the 02 sensors at that time. For the misfire on cyl.#3 I replaced plugs wires and coil pack. It’s all new. Fired it up . Same rough idle as before. I pulled that number 3 plug, no gas was on it not dirty at all as all the other plugs were. I pulled the intake off and pulled the #3 injector and replaced it. I also took off the valve cover on that side to check the valve was opening and closing. No issues there no broken springs or anything , all is well there. Anyway I put it all together, fired it back up and same crappy idle. Now I have p0113 code a po303 code a po108 code a po123 code a po175 code and a po155 code. One of those is for fuel pressure. I have a leak on one of the injectors. Have to tear it down and fix that. Also I pulled the #3 plug again and it’s as clean as it was when I installed it. I’m at a loss right now. Any words of wisdom? Bad wire at the #3 injector?? Really frustrating. [/QUOTE]
