Dave: Idle Air Controller. Fly by wire cars often do not have one and open the throttle plate directly. TPS (throttle position sensor) can be monitored with Torque Pro.


ps personal opinion but when you have a computer car that a dealer does not want to see, having a good scan tool is essential. Since the Crossfire is really a Mercedes R170/SLK320 that never forgets anythingyou can double that.


Only one I have found better than Torque Pro is the iCarsoft MBII (not i980) and it is not perfect (no logging capability and photographing screens is a pain) but can read/reset the Crossfire internal systems..


MBII is U$150 but a dealer visit for diagnosis can cost that. I just consider scanners to be essential tools.
