Power cuts to half, but today, stopped completely. Turned car off, sat a few minutes and restarted. It got me home. I have read this is an issue on Chevrolet's. Before i get ripped off, what do i look for? I have heard throttle body sensor, accelerator pedal, and other fixes. Please help

Good morning,

There is a fault code stored for the issue in the PCM.

You can have it checked for free at a parts store and once I know that code, it will narrow the area of failure.

Yes, the throttle body and the pedal sensor are common but they are expensive guesses.
