Probably the IAC. That'd be the first thing to check.

ya replace your IAC. it is on the side of your throttle body. and also make sure your voltage is correct on your TPS. the TPS is on the top of the throttle body.

there is no set screw on your IAC. that is non adjustable. but the throttle positioning sensor (TPS) is on top of your throttle body. that is what is adjustable. you check it by using a digital volt meter and ground the black wire and then probe the green wire on your TPS to check your voltage. it should be .99 volts. it is kinds a pain in the ass to check but it makes a big difference
