Ok. So from the sounds of this and the other post you have made you are really green at wrenching/jeeps. No biggie we all have to start some where. Now you haven't in any post I have read given your symptoms of what is happening. Is it bucking/crazy hesitation. Idle all over the place?  You can remove the t body with the 4 bolts on top, remove t cable/kickdown cable, both harnesses and voila it should come out as a unit. Then you can remove the sensors (torx a 15 or 20) clean your t body and sensors/replace them. A tps can be had at parts source for 55 (yj price, tjs are different wiring is opposite).  Iac is more, but I wouldn't throw parts at it unless you know your problem.   Which brings me to codes, have any?  Have you done the 3 key , on off three times thingy?  Or an obd2 scanner?

I still say tps but that would have thrown a code

yes and it throws a po-132 code... well we took the throttle body off cleaned the inside, the idle/air put it back together works decent now still hesitates alot but no stalling so its getting better

Right-o...if it's still hesitating I would seriously look at replacing your O2 sensors. They can fail and not throw codes.
Mine was a stuttering, smoking, bucking pile of crap until I replaced them...Smooth as silk now.
