Default I can't find the idle air control valve in my 1989 toyota.?
I know the iac is on the throttle body but I have no idea where that is either! I can't find any online motor diagrams or anything that will help online

The throttle body is on top of the engine. Find your cars air cleaner, it is usually right under that, or connected to it via a plastic duct that all you have to do is follow and it will lead you straight to it.

the TB unit is where the intake ducting attaches to the engine and it is bolted to the intake upper manifold plenum















































and that is where they always are















































it is a valve































it is attached to the TB unit with two screws or bolts usually

Hi so the only people will know is a dealer who could point out where it is if it has one.
