If you look on the passenger side of the throttle body, you will see the IAC sensor sticking out of the bottom (of the throttle body). I don't have a camera with me, but the URL below has an illustration...

Hope this helps.
Best of luck.

I'm not firmiliar with how to set the idle...
but the IAC is below the TPS sensor toward the front of the throttle body.

it should be a square-ish connector with 4 prongs, and has a green rubber lip. It is the only wire's that go to the bottom of the TB.
