If it does at an idle, check for vacuum leaks and check the idle air control valve.

Nope.

Need a lot more details. Does it stall due to idle speed too low, or will it also stall while you're driving at highway speed? Was the battery recently disconnected or run dead? Is it hard to start unless you hold the gas pedal down 1/4"? Do you get the nice "idle flare-up" to 1500 rpm when you start the engine?
