Idle Air Control -No Screws?

[LibertyTC]

Well not what the Haynes manual shows: MY 04 is a little different.
No Screws- Special tool needed to remove it?

What's with this wiring?
The red tab get pushed back and that allows that bottom wiring to come off .

So what are you trying to do? I'm confused ???

 

[LibertyTC]

Want to clean the ports/ IAC Replace if cleaning does not work. The standard units shown in the Haynes manual have a simple two screw base for removal, so how does this one come apart?
Note as Canadian Export unit (Possibly Canadian Emissions) may have created this unusual IAC. Would the FSM have anything to add here?
Does this look different than what you have? Maybe it is bolted, but I sure can not see where with out a dental mirror. It looks moulded into the throttle body.
Going to have to get Ryan to look at his as it also is an 04 Canadian and see if his is the two screw unit or the same as mine.

I think your right and that it screws out... I don't see anything in the FSM that i have except for the one thats bolted to the throttle body, so thats different for sure!

As for the wiring connector you slide the red retainer back and then the connector will unlatch.

Thanks to Richd, some info was given that appears to indicate this IAC from NAPA.
I am going to have to feel around or get a dental mirror below the IAC to see the ONE bolt it probably has. My current guess without looking is the bolt is on the bottom right. It has two o-rings for sealing, indicating it pulls straight out. So no unscrewing this unusual IAC, it is also a completely aluminum enclosed body on this IAC.

I am on the road to removal and cleaning soon, as long as I can find bolt and get the right set up for tool to fit in there, really tight location probably. Ratchet, angled, tool my guess.
Hard to believe in this situation the FSM is adamant regarding two bolts on the IAC.

 

[kb0nly]

Hmm interesting... Yep it looks like the bolt is down on the bottom right when oriented like in your pictures.

I figured it would screw out if a special tool was needed. The FSM i have only seems to show the other style with two screws, and thats what mine has on it.

I just got back from a very stressful work shift. Ahh.. the peace and quiet of ratchet and Torx bits in hands, as massage therapy.
Lets just hope after spraying blaster at that singular torx bit, located at the very bottom of the IAC, hidden very well behind a hose, that I can massage it loose. Going to have to use a 1/4 socket wrench with torx bit I am sure of it. A hair dyer will assist in heating that hose to safely loosen & remove it out of the way. Suddenly I think I like your 2 screw set up better. Let the fun begin in the removal and cleaning process of the IAC port and plunger. More to follow hopefully with a few photos for everyone else to enjoy!
The big question is after cleaning, does this fix the varying idle, when stopping and also when giving it a few revs (Neutral/PArk) after it is warmed up, as it is suppose to stay at the 575 rpm idle, without surge ups to 900rpm? The Saga to follow, but hopefully not continue.

Easy test for the IAC................

At idle(warmed up) crank the steering wheel either direction,if the RPM's raise it's working like it's supposed to.

Thanks For That info....But....mine drops about 40 rpm and no bounce up at all
Can others PLEASE check their kj and see if their's go up after tuning the wheel? Not that I do not trust this info but have never noticed mine ever go up after tuning the wheel.
Maybe all our IAC are crapola like mine after 36,000 miles.

IAC Cleaning completed.
Seems to have helped. It was dirty/carbon everywhere at 36k miles. Seems to hold idle now, but only time will tell if this is truly fixed.

Well that fit's under the category of "what I did to the jeep"... after work today.

 

[autoboy454]

i am totally going to clean my IAC this afternoon, you have inspired me! Also gunna pull my MAP as I i think that may be gunked up also...

 

[Ry' N Jen]

See what ya started Tim!

 

[LibertyTC]

Re-The IAC, I was able to move the plunger easily downward with a Q-Tip, so I think there should be more resistance, Just PM'd TJ to see if that should be tough to press down. I see a new IAC installed in the near future.
DO not forget to clean the PCV , make sure it has suction while running, and it rattles freely or replace it too.
My interior throttle body collects carbon, it needs to get sprayed out every once in a while too.
Damn gas by-products leaves stuff plugged eventually !!
"That carbon has to go" ....for things to run more efficiently.
I am sure "YOU" and your KJ will feel better after that carbon is gone!

 

[Ry' N Jen]

Sorry to go off topic here...

After the discription Tim gave me...
I'll be looking into mine as well!

 

[LibertyTC]

Let your carbon be gone ...

 

[profdlp]

Five years late, but I thank you. Planning to do mine tomorrow. :favorites13:

 

[LibertyTC]

After 5 years, I want to see some photos! I bet it is going to be carbon city!
My original post was in 2010!! Where did the years go?

Tim,
Did you have an updated thread for this?

Cant remember, But I don't think we have an IAC post in the how to section.
I guess one of us should make one eh?

Yours or mine?

Would like to see some pics of what your ports & Iac looks like, after so many years of not cleaning! :icon_lol:
