Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello, my name is ***** ***** I'm here to help get your problem solved.
This code is related to the throttle body assembly, shop who said disconnecting mass airflow sensor should cause stall doesn't know what they are talking about because it shouldn't cause vehicle to stall. Inspect throttle body connector and wiring, clean ground G104, and if problem still exists replace throttle body assembly. Here is a picture of ground, let me know if you have questions. Thanks.
Here is one on ebay for $115, probably cheaper then Rockauto
