You know, that kind of sounds like a bad throttle position sensor. Here'* how to test it. https://www.gmforum.com/trouble-shooting-test-procedures-141/testing-tps-throttle-position-sensor-279319/

Another thing you can try is unplug your MAF. The engine will stumble and run rough, and you will get a SES light. But it should smooth out. If that happens and the engine runs right, the MAF is bad.
