Four different shops read the codes, two of which were full service Chevy Dealers, The codes said both the the shutter control and throttle body motors were bad. The Chevy Dealer mechanic i chose to work on the truck told me that he physically inspected the old throttle body motor with his tester after he removed it and confirmed the motor was not responsive. The shutter control motor also would not respond to his inputs but he was not able to remove the shutter because they had to order one.What were the codes?
I wanted to watch him test the throttle motor after he removed it but was not allowed back in the work area. The throttle body has already been replaced. The shutter control will be replaced next week when the part comes in.
After the mechanic installed the new throttle body, I cross examined him the best I could and feel reasonably satisfied that he is experienced, skilled and honest.
I would have replaced the throttle body myself but I do not have the equipment necessary to reset the ECM.
