So I have an '07 with a Vortech, headers and no cats that runs extremely rich. Apparently there might be something wrong with the passenger side O2 sensor wiring. Any suggestions ideally in Northern CO (I'm in Cheyenne, WY)? It would be nice to not coat the back of my Jeep in soot and gain gas mileage and proper performance. Thanks.

Do you have a trinity? If so buy a afr gauge and and log it and send it to one of the reputable tuners on this forum. Afr gauge is a must....especially up here now that its super cold and even the quality of gas changes in the winter. Pm if you have any other questions.
As others said get a wideband. I would contact either Johan or Jerseyboy and get them to start tuning it for you tho. They can get you a baseline that is probably more in line than what you have right now. My guess is that it was tuned at a lower elevation and then the truck was brought up here.
Thanks for the replies. I should've provided more info in my initial post. I believe the Jeep has been in CO from the beginning. I have a Predator that I sent logs to Johan with. The passenger side O2 for some reason reads 33% even at idle. The O2s have been replaced and Johan suggested that it's probably a wiring problem of some sort. I suck with electrical stuff and a shop locally couldn't figure out the issue. I've been meaning to pick up a wideband but didn't want to ruin the sensor if I wasn't able to get it fixed quickly. I'll probably pick one up and setup an appointment down there.
