hi jt,

to verify if its really the AAR, simply disconnect the hose, which is going from the AAR to the airplenum. When disconnected, the idle speed must raise to 1500 rpm.
There are some other sources of error, e.g. the temperature sensor, which senses the cold start condition and the cold start injector, which sprays additional fuel in the air plenum.
