So my idle gets really stupid when i turn on the air conditioning...Im not sure where the idle air control valve is, but is this it?

 

no thats your throttle positioning sensor. The IAC is on the other side of the throttle body almost on the bottom. Its a bitch to get out without taking off your TB but its doable... as far as your idle being crappy when you turn on your a/c you might want to check your alternator. I mean you're going to lose some power and see a dip in your idle with the use of a/c but if its really bad. I'd say its your alternator
