I went out and bought a new o2 sensor ($70 later) since my jeep had been stumbling at idle and running really rich. When the o2 sensor is unplugged, it runs fine. Anyway, I plugged it in and the jeep ran great, nice and smooth, better power and shifting, CEL is out after resetting computer.
After a 20 min. drive, CEL comes on and it starts doing the stumbling at idle and running really rich again. I can smell gas while I'm driving and carbon comes out of the tailpipe pretty heavily.
So, now it appears that my old o2 sensor might not be bad. When i pull the codes it's saying o2 heater and misfire. If I unplug the O2 sensor, the codes stay, but the jeep runs fine.
Any suggestions??? I'm about to go on a 4 hour road trip to go wheeling and would like to figure this out.
