who is running an idle air control motor on built ca's . i dont have one now and ive got it idling at about 900 rpm now but im just wondering what would happen if i hooked it up along with that thing thats connected to it before it goes into the intercooler piping? can those things handle power?

i have mine all hooked up including the idle up for AC ON

has a nice adjustment screw on the back to move up or down idle, by using a 10MM wrench.

it is attached to the intake mani......... why would you attach it to the IC piping?

is the piece that ups the idle for AC on that big odd shaped cylinder thing the bolts somewhere in front of the throttle body?

mine is not bolted on but it hangs down under the TB and has a connect to my intercooler pipe, and either 1 or 2 other fat hose connections.

you are talking about the thing that has the idle screw, AAC valve, FICD valve, etc. correct?

gabby, i think he means the hoses where it draws the air in from. those are supposed to be connected to the intake.

um yes, they can handle any power you make, but I removed mine and set idle with throttle body and a PFC.

No, it's supplied 12V+ when the ignition is on. When the AC system is activated it's provided a ground path, which opens the valve and increases the idle.

Yea, if you put 12V across it with the engine off, you should hear it click.
