Is your rpms jumping up and down sporadically. If so, than it's most likely your tps. I've replaced mine twice. First time it just went bad from wear, the second time it got it wet inside when I had my intake off for cleaning and it got fried. You can us a voltmeter and check it. You put in the positive and neg prongs into two of the three wires going into the sensor and check to see it read up to .5 volts and back down to 0 as you open and close the throttle. If it reads a full .5 volts at open I belive, than it's ok. If it's less, than it's no good. Or you can just buy one for $30 or so and see if that works too.

I'm sure someone will correct me if I am wrong on something...

If this doesn't solve your problem, than maybe I can stop by after the mounds on Sat. and let you swap mine over to see. Let me know. ~ Josh

that it pretty much the problem exactly, but it isn't all the time. I can drive a mile fine, then it will start jumping around. normal crusing is around 2200r. it will go up down up down, then end up at 2700 for 10 seconds, then down to 2400, bounce around some mroe then back to 2200 then fine for another few miles.

yep, well I'd say that's gotta be your problem. Same thing mine did. If you can spare the $30-$40 than just buy a new tps, slap it on and your good to go. If you go to autozone they will plug in their code reader and confirm what sensor it is for sure, for free. This is assuming you don't have a code reader. I bet you it's deff. that tps sensor though. So go to autozone and get yourself a new one. You might have to reset your computer by pulling off your battery terminal for a few minutes, than give it some time while your engine is runnning for your computer to recheck and reset it's perameters. Than your back to normal!!!

Ryan, now that you got your jeep on the road, are you gonna go to the mounds on Sat. for some of bruce's chilli. It will be a good time! My brother Trav (the guy you built the bumper for) and I are going.
