Idle Problem in 305 TPI

I have a 1986 Trans Am with the 305 TPI that seems to have a problem where it won't idle at all. When I start it, the engine fires, but will just die, and not even try to run. If I open up the throttle when I start it, it runs normally, until I let off, and again, it just quits, like I turned the key off. Any ideas? At first I thought it possibly could be a mass air flow sensor issue, but then I figured if it was an issue with that, it would probably try to idle. Any help is greatly appreciated.

Yes do some trouble shooting on ether the mas or the tps(voltage should be eather .54 or a littel higher on the tps for better thottle responce)
