1991 firebird 305tpi automatic trans

i drove the car fine the other day with no problems, i go to start it last night and it cranks over fine and starts but i need to give it and hold gas to keep it running. as soon as i let off the gas to let it just idle the car stalls out. start it and again hold gas it runs to letting off the gas and the cars lights go dim and it stalls out.

any ideas this ever happen to anyone?

someone told me alternator... someone told me idle control valve.. but both are relatively new from the local Autozone

thanks
