The IAC is just under the throttle butterfly/throttle butterfly housing. The EGR is at the rear of the intake manifold toward the throttle housing. A website that has a lot of information on this engine and theory straight from the Toyota factory training manuals is
click tech articles from menu on left.
Your engine is the same as a Toyota Corolla.
Also look on Autozone's website its a little hard to find but they have some workshop manuals free on line. I think you have to register your email address.
