97 Xj aw4... So when I check codes on the dash I keep getting a 21 which is o2 related... I replace both sensors and still has the code... So my issue started last week on Fordyce... My buddy threw a rod in the first water crossing and I had to tow him back to staging area which is nasty terrain to tow a Yj on 40's... I even went through the crossing with no issues... So I'm towing him out and jeep is running fine... A bit hot but fine... Then all of a sudden my jeep just starts running like crap at idle and under throttle unless its alot of throttle... If I shut off the jeep and start it right back on it runs fine for a min or two but goes right back to crap... So needless to say I had to stop all the time and restart all the way back to the staging area... It started doing so while I was winching a lot... I was giving winching breaks but I had the voltage light come on a few hard pulls and wondering if I could fried something? I'd turn winch off and the voltage would go back to normal though... Also while all this was happening when I would somtimes try and pull him my trans would just slip which was bothering me also...Fluid was full and clean also cuz I checked... It would slip in forward gear and most of the time in reverse...
It's home and I've been working on it and replaced both o2s and still runs like crap... My obd2 port is being stupid and won't read so I'm just checking codes from the dash.... I was just messing with it and the trans was slipping yet again in reverse in 4lo... I also changed the fluid incase water was in it which wasnt the case it was clean... Any ideas? I really need to figure out the obd2 port not reading which ill do tomorrow... Thanks in advance for any ideas!
