recent woes

Greetings all! I've been a Jeep owner for 5 years now and its been nothing but the best of times. I drive her anywhere and anytime I can. Its an '05 Wrangler X with about 90k miles on it and the other day my check engine light came on.

The problem is as follows: When I am in a lower gear, 1-3, and I accelerate up around 2500 rpms, my jeep starts to buck. It even happened in 5th once as I was preparing to pass someone on the highway. (I thought it was the gears slipping at first bc I knew I was due for a clutch, but after I replaced it the problem persisted.) Its spitting out a code for the cam sensor (P0344), but I changed that and the same thing happens. Once the jeep warms up, the light comes on and the bucking will happen. She even stalled out on me once. Any suggestions?

Have you changed the spark plugs, I think you should do it every 30k. I did mine when it had 30k and forgot to do it at 60k and now it has 82k and I can feel it miss now and then. Plan on doing it this weekend.

Retired my 94 YJ 4cyl 5spd @ 200K
Now in a 04 TJ 4cyl 5spd CV @120K+
Both as a commuter vehicle in NW, NJ
April 2012.downsized and now a 99er.

I'll give that a shot and let you know if it works. Thanks for the advice! I had mentioned to a friend of mine that I was going to check the spark plugs and he strongly cautioned me about threading (treading?) them when I put the plugs back in. Is this something that is easily screwed up, or is he just being over cautious?

Thank you!

When replacing the plugs spray the threads with a LITTLE bit of WD40 or something similar. Then put them in by hand as tight as possible before you use a socket on them. That should keep them from cross-threading

Thanks again for the helpful replies.
Update: I changed the spark plugs and the CPS...and the problem remained. I took her for a test spin after the work and right on cue, a few minutes into the ride while pushing it in third gear up around 2500rpms, the check engine light came on and she bucked on me.

I took it to get an OBDII reading and the same code was being put out for the cam shaft position sensor, which my mechanic originally changed about a week ago. The employee at Advance gave me some new input. He said that it was reading a failure at the cam sensor in circuit A (or something), which means that maybe its not so much the sensor as the receptor its plugged into?

I fiddled with it and now its not happening. I dont know. Any input or feedback? Could it be a loose wire or dirty connection?

Need to establish what else is in that circuit. but yes it could be a bad connection, or faulty wire, or another part that is in the CPS circuit.

I don't have a wiring diagram, so I can't say what to test.

If I were you I'd search every jeep forum for the OBDII code you posted, and see what you come up with, then go from there. I'm sure its been covered on one of the forums.

Time to go to the dealer on that one. There is a recall on them for that reason. The distributor gear gets premature wear and starts to chew everything up.

I went and it should be right as rain by next week. But was there a definite recall?? If there was, should I have to shell out the money for the redesigned part and installation?
