muddinisfun Problem solved- The prick that sold me the the jeep cleared the codes before I bought it. Took it to the spealership and this is what was found.
1 bad 02 sensor bank 2/2, 2 bad cats-covered under the federal emissions warranty, evap line had a hole in it on top of the tank.

bondosgto Replace all O2's, use only oem/ntk/ngk, remove negative battery terminal for ten minutes. If you are having issues with one I guarantee you will have issues with more soon.

I've had a couple of codes on my 2002 wrangler with the most resent being p0158. This code and the last(can remember which one) I was able to fix by just looking at the hoses by the air/whatever devices and each time found one that was split. The p0158 was a L shaped hose and I taped it and the error was gone in a few runs.
So, I always would start with looking for cracked and split rubber.

My first two quetions would be...

Have you done any offroading in water?

How many miles do you have on the Jeep?
It has 75 k on it and has been off roading by previous owner so I would assume yes
