O2 sensor looks a little tweaked
My Jeep is a 96 sport 4.0L AW4.
Just wondering if anyone has ever had problems with the front DS hitting the upstream O2 sensor? I have about 3" of lift on it.
The CEL came on this weekend while wheeling in mud and rocks. When I got home I ran codes on it and 12 21 34 21 55 came up in that order. Ran it a few times to see if I was reading them correctly since 21 came up twice.
I replaced the o2 sensor which was loose and looked rather tweaked like it had been in contact with something. Or I just tightened it too tight when I put it in about a year ago.
Thanks
