My jeep is ideling too fast. I took a road trip, about 100miles. When I returned to normal speeds my jeep kept ideling fast. when I put it into park it revved up and when i turned off the engine it shook and made an unhappy sound. I let it cool off and started it again. again it is ideling too fast.

This car has an automatically controlled idle speed system, so when you have a problem like this you must have the dealer run what is called an active engine running test, the test puts the engine through the paces and returns data to show possible problems.
hi katie
dealers are a pain in the but.t we all know unfortunetly there are many things that can go wrong in an engine these days all the electronics are a nightmare and people do have to pay allot of money to get them sorted out, by what you are saying and verry good description as well i might add, it actually sounds more like the TP sensor ( throtle possitionsensor ) it wouldnt be the 02 sensor as that would not make a difference to the rpm's, nore crank sensor, speed sensor ( there are 2 of these) it might be but i would be a bit hessitant and changing it first as normally that just sends signal to the speedo ( front one, posistion1 ) and the rear one records road speed, so i cant see it being that one, i personaly would go for a test on the TP sensor as this would definatley make the symptoms you are describing, the ECM could also be a problem if this has got "dirty software" in it this could cause loads of faults, you would then need to get the ECM ( engine control moduel ) re-mapped to get it back to normal, well i think that would be just about enough to be getting on with, so first i would check out ECM, if ok the the TP, then the speed sensor....hope this helps call back if you find the fault as well as if you dont ok..
Sounds like you have another Vacum Leak, What is this thing idleing speed AT...?????? Vacum Leak Cause high Fast Idel...so i would check futher into more leaks
have a shop check the tension on the choke settings in the morning before car is started,and reset fast idle on choke settings,then when car is run and heated up it will trip off the choke settings and fast idle and return back to normal settings
the iac probably has carbon built up around it this controls the idle speed try cleaning it first,if not it could be a bad iac or a vaccum leak that the iac takes some time to compensate for to control idle.
My wife complained about the same thing on her BMW. After driving it on a long road trip in the rain, we realized that if you just turn it to the first setting, the wipers automatically speed up, and slow down as rain increases/decreases.
