Can I Clean My Jeep 4.0l Iac

Chris, for whatever reason it may be, no images will come upward

Thank You lot, Sir., and now I will have to investigate this equally well- as time allows. Could be a twenty-four hour period to a month or so but it is so awesome to get fixes to problems and so fast here. When I do get to information technology I will post the results.

An update on this and a huge thanks to all involved; this was an outcome I posted in the full general forum I retrieve- my tj would idle loftier enough to climb a steep hill off road,but only after the motor was hot. Engage the clutch and get loftier revs till the motor got air-cooled and the idle returned to normal. I finally took the iac valve off today and it was gunked up just as the above "earlier" picture. I cleaned information technology with gum cutter and got the parts in the assembly moving over again, re-assembled and took her for a test ride. No more high idle effect when the motor is upwardly to temp. A fairly easy repair and no price involved. Thanks once more!

Well, I've had this issue off and on for awhile. I've ordered a new IAC and TPS sensor, but and so I saw this write upwardly. I took everything apart and cleaned everything per these instructions, only I still accept the event. Hopefully when the new sensor gets here, that'll fix it.

But in case, is there annihilation else it could be?
