I know you guys think I'm FOS, butI use SeaFoam in my oil/gas ans my IAC has not stuck again. Mabye I was lucky, mabye not. All I know my high throttle started operating again when the AC pump kicked in.

(1/4 inch is recommended, 1/2 inch is hard to use in tight spaces)
Thanks for the great write-up!!

My 1/4-inch Craftsman ratchet was too large for the bottom IAC bolt. I used a mini combination wrench (8mm or 5/16-inch). You don't need alot of leverage - IAC bolts are only torqued hand-tight. I also found a telescoping mirror to be helpful.

Before starting, grab a handful of Q-tips -- you'll need them to help the cleaning fluid do its job.

This job is definitely do-able -- but requires PATIENCE!!

I prefer the easy way: idle the engine and squirt the cleaner in the throttle bypass until it stalls and let it sit for an hour. I know your way is better, but my way is easy enough to do every oil change or so.

got my IAC removed...went to look back at these pics to compare...there gone..

My iac was pretty clean...I got a replacement, just in case....the new one has a spring inside. Installed it and the motor REVed high..took a while for it to idle down....
once it calmed down it was nice and smooth..UNTIL I TOUCHED THE THROTTLE....it peaked again in gear!
Took it for a spin....it was like having the cruise control on...gonna take it off, and put the old on back and see if the new one was bad..

anyone else have this issue?..

Rob,
I'm sorry to say that I have had the same issue. Replaced the IAC with a new one but could not the gasket on. (major mistake). now when i start the car it revs way too high for like 5 minutes and then comes to a normal idle. But the thing is messed up because it accelerates on its own at 40 mph with my foot off the gas.

I will remove this IAC and put the gasket on like i should have. According to the experts/moderators on this site, a vacuum leak around the gasket can be the cause. Since all i fooled with was the IAC (plus cleaning TB) it appears the gasket (lack-of) is implicated.

I'll report back whhat happens with the new gasket.

Sugestion???

Buy the unit through FMC because of the stricter standards they require the IAC manufacturer to adhere to. Fix it once and ferget it.

Can the pictures from the first post be put back up? I live about 3 hours away from the car and would like to know what everything looks like before i clean or replace the IAC valve.
