Beautiful day today, so I take the vette back to work from lunch, and, on the way home it is running great and when I accelerate, it falls flat on it's face and acts like it is not getting fuel or something. I had to pump the accelerator to get it home. The check engine light came on and when I got home I checked the codes and got 22 (TPS circuit-signal voltage low) and 33 (Mass Air Flow). I went to check the TPS voltage per the Haynes manual with the jumper wires and could never get a voltage reading. Does that mean the TPS is done? Will the car even run if there is no voltage to the TPS? I started it up again and it idled and ran, but the check engine light came on again after I had disconnected the battery and re-connected. I had this problem a few months ago and replaced the MAF relay and the burn-off relay, located behind the battery and it seemed to cure the problem. Is it the relays again, or is it the TPS that is faulty, or what? Help?
