Hit a bump and engine cut out

So I was driving through my neighborhood and hit a decent size pot hole. I've hit it many times before and never had any problems, but today when I hit it the engine cut out...or something lol It was still running, but when I pushed the gas nothing happened. I pushed the gas several times and eventually when I pushed the clutch in everything went back to normal. I turned around and was able to repeat the issue with the same results.

Also, it caused my check engine light to come on, but I won't be able to pull the codes for a couple days.

Any ideas?

Maybe there's a loose wire somewhere? The TPS wire perhaps? I know in my Cherokee when the TPS went and you hit the gas it just kinda chugged along

The YJ is in Rebuild Mode

I just had this same problem with my TJ. I would ride over bumps and the engine would almost cut-out. One night it completely died on me. Took it to the dealer and said it was the crank sensor and O2 sensor wiring. In the end it could be many things that cause such a dilemma. Check all the sensors along the engine first. Check your TPS sensor most importantly. And you might want to clean out the throttle body. Get this checked out as soon as possible and try and not drive too far from home because it might just die on you

Thanks, I was thinking along those same lines of either a loose wire, bad tps or cps. I'm going to try to pull the codes this weekend and go from there. Has anyone else had this problem?

Well I pulled the codes yesterday, and there were four PO201 - PO204 which are injector malfunction codes for each cylinder. I'm thinking there is a loose wire since they all cut out at the same time and work fine afterward.
