Hi there. My name is ***** ***** I am one of the GM techs here. Readying your description, it sounds to me like you have a bad wire or connection in the throttle position sensor circuit. See the attached diagram. You will want to start at the TPS connector, look for any damaged wires or corrosion build it. If that is good, go to the PCM and check pins 61, 66, and 33. Looking for any visual damage to the connector or pins or any corrosion build up. If all is well you will need a DMM 9digital multimeter) to continue the diag process. Let me know if you have one, and I will tell you how to proceed. - Chris
