had it replaced 1000mi ago (ish) Went bad again. Any Idea what's causing this?? I AM driving it really rough, just because in high winds I have to keep the gas pedal floored to stay in the flow of traffic. So it's driven at max blast A LOT, I don't know if that will do anything, or how to solve the problem.

bad cat?

Upstream from the Cat.

how are you determining the sensor is bad

6/21/2011 7:41:38 PM

Code reader.. last time.. This time: same symptoms, so I just assumed.. I haven't read it yet

6/21/2011 8:25:46 PM

I always fucked mine up when i got water in my exhaust.

Post the actual code. P****

P0131 Same as last time

Sure the harness is ok?

6/21/2011 10:02:06 PM

yup.. looked at that, I'm looking to see if it blew a fuse.. but I can't find a fusebox diagram to tell me which fuse to check. Still let's assume the fuse is fine... what would be causing me to burn through O2 Sensors?

running really really rich or possibly really really lean. hard to believe a jeep could run lean enough to have egt's that high though

Do you have higher gears in it, did you gut the cat?

6/22/2011 12:56:59 AM

It's all stock, except for the lift and tires. Is it possible that me driving it with the gas pedal floored all the time is doing it?

6/22/2011 9:50:20 AM

is it throwing any codes for fuel mix or is that the only code?

6/22/2011 10:00:55 AM

its its the 2.5l then yes.

6/22/2011 11:36:17 AM

Found it. Exhaust leak, and yes its calling out a lean code too. This is so frustrating b/c I had a guy look for an exhaust leak after I replaced the O2 sensor the first time

If you can't hear an exhaust leak in a wrangler you shouldn't be driving a car.
