I have a 1991 Z28 Camaro, V8, Manual 5 speed. The problem I'm having is that when I turn the engine on, if I let go of the gas pedal, the car dies on me. The engine dies when I stop on a red light, even when I turn the gear, or make a turn. About the only time the engine doesn't die on me is when I have the foot on the gas pedal. Does anyone have an idea what the problem could be? THX'S.

Large vacuum leaks will do it too. Do a thorough check to make sure there are no loose hoses or cracked fittings - there were a lot of them in '91.

If it's injected, go after the Idle Air Control motor - that's what admits air into the intake plenum for idle; if it has died or is stuck closed, it will die instantly at idle throttle opening. Could also be a bad Throttle Position Sensor, as the lowest opening contact on it is what triggers the computer to operate the IAC motor for idle.

I had an 86 Iroc that did the same thing. It would die at a stop-light or when slowing down to make a turn. Even when the engine was warm, if I went into a store,when I came out I had to keep my foot on the gas while putting it in reverse or it would die. My service engine light was on. Checked it out, and it indicated the mass air flow sensor. Replaced it and the problem was solved. Hope this helps?
