just got done cleaning! it was a breeze, also found out the PO had put a throttle body spacer thing in... I know they don't help you significantly, but would I be better off leaving it on or taking off?

one torx screw on the 05 and 06 models..... instead of a gasket the new one uses a rubber o-ring. After you remove the torx screw twist the IAC back and forth while gently pulling it out.

I just did this clean out this weekend. Seemed to work perfectly. However when i jumped on the highway (i had a 2 hour drive) My jeep was vibrating a lot. It was vibrating the front end not the steering. After an hour into the drive my engine light came on. Went to Auto Zone found out it was my TPS. Would that cause this??

I doubt it's coincidence. did you remove the TPS or soak it with cleaner? When I cleaned mine I really only cleaned the throttle body, the butterfly valve, and the air mass sensor. I didn't "clean" the TPS since it is probably just a simple sensor that works off the butterfly valve axis position.

I thought i followed the directions and just cleaned what was said to clean. The IAC, throttle body, butterfly valve, and the MAP hose. Don't think i really touched the TPS. I am going to try to take the connector off and reconnect when i get off work. I imagine the check engine light wont go off though i will need to get it cleared.

Buddy of my here at work also suggested i put my jeep in neutral and get my engine up to speed to rule out any possibilities with my wheels.

Disconnect the battery for 15-20 mins and see what happens. That will reset any codes. Make sure the TPS plug is in all the way and make sure the contacts are clean. Also make sure the 2 screws holding it in are tight. Same for the IAC

Thanks for the write-up!

Did this yesterday, man it was nasty in there. Definitely idles smoother now...

Question though: I didn't have a paper gasket or any remnants of anything between the throttle body and the manifold. I hadn't had any problems before and haven't noticed any since, should I just leave it? (If it isn't broken, don't fix it).. Or should I track one down? (It is indeed 'broken' without a gasket)

If we use a paper TB gasket, does the gasket require any type of gasket sealer?
