Since my Cherokee is only a buggy and I'm having trouble tearing off the front 02 sensor, I'm looking for a 'dummy' sensor. One that I can just plug into the wire harness and will send a signal to the computer.
I've heard of them, but don't know anything else about them.
Anyone know where I can get one (or two?)

The front (upstream) is needed to adjust fuel trims. The downsteam after cat is only used to monitor Cat effiecency and can be "fooled" Without the upstream it will stay in open loop and run like crap.

Dang..... what happened was the upstream sensor got knocked off and it started running like crap.
Does anyone make a shorter sensor, or one with the wires coming out at a 90* angle.
It could have just been a rock that took it out last time, but I'd rather not deal with that again.
Maybe a new bung is in order...

Rick move it up under your skid plate, this will protect it.

Can't you mount it on the top side of the tube?
