Is your TPS voltage low code showing any other codes related to your stalling issue? Cleaning the connector as IHBD suggested sounds like a good idea. Not to state the obvious, but any stalling issues need to be diagnosed as to either fuel or fire, and then go from there. Do you have any idea given your history with the car which is the more likely?

Man, I wish I knew more Corvette-specific diagnostics. You say you blew the head gaskets. Those don't usually give way for no reason. Do you have any idea why?
I would say your idle problem is separate from your low/no voltage going to the TPS. I would think a related electrical problem with your crank sensor (for instance) giving you a rough idle would throw a code or two. Is your Opti nice and dry? I would pull a plug and see how they look. Probably one from the driver's side is the easiest to get to. You could see if they're getting gas at least or are fouled in some way. Easy things first. Wish I could be more helpful.
Keep us posted.
