Idle Air Controller - Trying to Clean for Rough Idle - Need Help
I have been experiencing rough idle and a little sputtering just as I press down on the throttle. Runs fine once I'm up over about 900 - 1000 RPM.
I've seen Jerry, Wheelin98TJ, and others post recommendations to clean the IAC plunger, and I'm finally trying to get to it tonight.
Here is the picture of the throttle body Wheelin98 posted in another thread, and it looks pretty much the same as the picture in my FSM:
My problem is this: notice that where the label points to Idle Air Control Module, the arrow points directly at one of two Torx screws that are supposed to hold the IAC to the throttle body. My IAC does not have these screws. And no, they're not missing - there are no holes for these screws. I see where the IAC is two pieces, with one side cast into the throttle body. Does the IAC module thread into the throttle body on my 2005?
I don't want to force anything, and I don't want to remove the TB if I can avoid it and then have to replace the gasket.
Yeah, I know - and it shows pretty much the same as the pic from my '05 FSM. But I'm telling you - the screws aren't there. I have a tendency to be a bull in a china closet - so I'm trying to hold off until I get some advice.
OK, here are a couple of pics. You can see that I've disconnected the elctrical connections for the IAC & TPS. The IAC module is complete cylindrical, no screws - not even the ears for the screws as shown on the diagram I posted.
Yea thats must have been a change in 05 , how bout bolts that hold it to the throttle body Can't see if it has any at that angle and if it did it would be a pita to get off with out having the TB off.
looks liek it may turn off But that could just break it
No screws or bolts on it. But I'm afraid of breaking it. If it's threaded in, I don't know which way it turns, or how tight it is. I don't know how strong the bolt ears hold the throttle body down are, being that they're cast. And I don't want to take the throttle body off if I don't have too because of the gasket. The stealerships around here never have jack, so I'd have to wait for it.
My 06 is the same as yours, there is one torx screw down low on the fuel rail side. The IAC has 2 o-rings on it, and will feel like it should not pull out. Just pull it straight back and hard.
