idle control motors are prone to getting dirty.. just remove then and spray em out with carb-cleaner or brake cleaner..then reinstall, your car should be back up and idling smooth in no time.
not sure if this is common on a subaru.. i dont have a subaru idle motor anymore..so i wouldnt know.(damn engine swap..some things have to be custom...)
how many wires does the WR idle motor have going into it?
anyone know if its like my 2.2 had.. 1 power, and 2 grounds?
