Just as the subject says. I have haynes manual but it shows it on some part and I don't know where that is.

Re: Where is the IAC - How Can i check it
the IAC (Idle Air Control valve) is located on the side of the throtle body. Do not confuse it with the Throttle Position Sensor which is connected to the throttle blade. The throttle body is located between the intake manifold and the air box.

Re: Where is the IAC - How Can i check it
Best thiing is to try and clean it and the port in sits in up inside the intake.
Dont push or turn the tip/end of the IAC. It will knock it out of calibration, resulting in a worse idle or no start. They arent cheap  here is a pic of that IAC. IAC If that doesnt work, I can locate a testing procedure. Heres a pic of the location, yello arrow points to the IAC. under hood location
