1992 Stalling

My 1992 Corvette has a severe stalling problem, it is hit and miss. It will run fine for a couple days then start. When you slow down it will die. It seem to run ok at higher speeds. I have had the plugs, plug wires, and distributor replaced and still stalling. Could it be the electric fuel pump?

possibly IAC (Idle Air Control) Valve replacement, give it a shot while your throwing $ at it...(it is cheap and an easy job on the throtle body)
