I have a 2005 6 cylinder tj. I bought it about a year and a half ago with 84k miles on it. It now has 95k. About a month after I bought it the issues started. First I had to replace the catalytic converter. After several attempts to replace 02 sensors to check the cel to clear, I bit the bullet and replaced the cat system. Problem solved. Then, shortly after that I get check engine light for cam and crank sensor. So, I replace the opda. Problem solved. About 6 months after that I get a cel for cylinder 3 misfire.
Did the heat shield tsb fix. Problem solved. Then, a year later light comes on for cam sensor. Mechanic checked everything and said the cam was off by about 15 degrees, he adjusted it, but the cel came back for cam sensor. I found the old oem sensor I had from the old opda and replaced it with the crown sensor. Problem solved. Then a month later my Jeep starts to stutter and stall while idling, the cel would flicker as the Jeep stuttered, but no code stays stored. When I started the Jeep back up the light is off.
I then thought my issue was with the ecu. I sent it to G7 and they sent it back saying they fixed it and that a wire on the Jeep shorted out the a transistor on the board. I checked all wires looked fine. Reinstalled the ecu and the problem persisted. I took the Jeep to the dealership. They said the thought a wire on the engine wiring harness was stretching and cutting in and out, since Jeep doesn't make wiring harnesses for '05 Jeeps, they couldn't do anything but say that I should try to find a used harness off another Jeep, but hey, they weren't going to charge me. Haha what a load of shit. Thinking maybe I did something to the cam sensor wire connectors, I replaced the connector, that did nothing, so I took the Jeep to an auto electrician near me and they said they didn't think anything was wrong with the wiring harness.
They switched the fuel pump relay with the horn relay thinking maybe the issue was with the fuel relay. I picked up the Jeep and on the way home the cel came on and the Jeep went into limp mode. Checked the code and found it was for the cam sensor, again. Thinking maybe when I replaced the connector I did it wrong, so I did it again and the code went, but it was still stuttering and stalling. I brought it back to the shop. They checked and saw that the cam chain had a lot of play in it (they even sent me a video of how much play was there).
They replaced the chain and now the cel continues to come on for the cam sensor. I am at a loss with this thing, and my fear is that the gear on the came is worn from the bad opda. Any thoughts or suggestions would be greatly appreciated. Thanks for sticking it out and reading all of this. Haha
