Idle air motor

They can be found on ebay under seller name socal_brock (there is an underline between the name socal_brock). He has excellent original Cadillac parts, I've used before. He also sells the ECU Computer Coolant Sensor, Manifold Air Temp Sensor, TPS throttle position switch, Speed Sensor (distributor trigger) signals correct injection group to spray.
