Engine stalls

I have a 1991 Trans am GTA 305 TPI. When the engine warms up the engine tends to want to stall or get a really low idle when you tap the gas at an idle. For example if you are waiting in a line and want to move forward a short distance and touch the gas and let off it wants to stall. If anyone has any ideas or have seen this before let me know.

Thanks

i would check the basics -- plugs, wire cap etc

check your voltage on the TPS, check the IAC

vacuum leaks and so on

Re: Engine stalls

I have replaced the IAC because thats what i thought it was but did not change anything. It always starts right back up and only does it when it get warms at low idle and i even removed the plug and adjusted the throttle blade open as far as it would go and still no change
