That's what it's supposed to do, Leland. Sounds like your AAV is working, since that device is responsible for increased idle during warmup. This time of year, the last thing that a Boise-dweller needs is a car that has no choke or idle increase during warmup. If these systems were not working, you would need to keep your foot on the gas for a few minutes, in the mornings. It would die at intersections and perhaps exercise your popoff valve as well.
