Can someone help me find info on cleaning the IAC ?
2000 Ranger , 2wd , auto - 2.5L . This is my dads truck , I have been helping him get it ready for daily driving duties. He got a more than fair deal on it but we have replaced the engine , upper control arms , lower ball joints and sway bar link . The engine (99k miles ) seems to be doing well but had sat at the salvage yard for a while before we installed it. It acts like the IAC is sticking ( no cel ) as the idle is a bit low and surges somewhat when under load ( wheel turned , placed in gear , electrical load ect. ) . Does anyone know where I can find some info about cleaning it ?

Yeah when I just unplugged it, the truck would basically sputter and die (before I set the idle screw to compensate). I didn't look too much into a vacuum leak or something like that to be honest, but I seemed to only have the issue when running the a/c. It very well may be dirty though, since I didn't try really thoroughly to clean it.

After cleaning mine I realized there doesn't appear to be a wax/thermal coating to worry about so I'd say carb/TB cleaner would be best. I started by using MAF cleaner but it wasn't strong enough though it is the only safe thing to clean the MAF and IAT . Carb cleaner cleaned it right up. The way they are designed it wouldn't take much build up to stop it working right. Be aware of the gasket , not sure how hard it would be to find one but one could be made.
red_rider ; Sounds like the IAC is your problem as it bumps up the idle when a load ( AC , PS electrical ect. ) is placed on the engine . You can also clean your throttle body if you see build up near the throttle blade . You may have to readjust the main screw after you get it sorted / clean .
