Hello Delaney

If there is any doubt or further explanation needed on my answer, just reply on this thread and I will get back with you. I am here to help you, so I want to make sure your satisfied.

 

I also feel like this is the idle air control valve if the idle speed is dropping to low when AC is used. It also would not hurt to do a system cleanup shown below.

My Car also is Idling at a High RMP, when it warms up it increases to about 1700RPM. Is this because of the IAC motor?

Accepted Answer

Yes this can also be caused by the IAC. Another symptom of high idle is vacuum or PCV hose leaks so check these as well since they cause lean concerns which results in more fuel added and more fuel added means higher rpms.
