Having the stereotypical high idle issues usually associated with an IAC valve possibly either going bad or just overly "gunked" up. The engine is a 4A-FE2 (?) Basically a Toyota Corolla engine
I've gone through seemingly every inch of the engine compartment, looked through various web-sites (except this one), part stores and manuals to try and find it; but I cannot seem to find anything that looks like what I believe an IAC valve should look like.
to try and reduce the high idle: I've cleaned the throttle body - as much as I could - I found and cleaned a part that I thought was the IAC valve. It had an electrical connector with a couple of small vaccuum connectors(one that "plugged" into the manifold? On the opposite end away from the throttle body) BUT it had NO visible moving part and no way to get into the housing.(Please see the attached :-)
I also turned the idle adjustment screw pretty much all the way down and adjusted the throttle cable, because it did not appear that the "butterfly" valve of the TB was closing all the way (even after I cleaned all the gunk :-)
and while these procedures helped a bit.I noticed the higher idle was still trying to reassert itself
Sooo. I'm stuck. Apparently I did not locate the IAC valve and would VERY much appreciate your help with location and other ideas
have the same problem?
