MY WON'T IDLE AFTER IT WARMS UP

1991 Chevrolet Truck • 24,400 miles

My 1991 chevy silverado wont idle. It idles when cold but when it warms up it wont idle when you put it in gear or come to a slow down or stop. I have replaced the IAC, coolant temp. Switch, worked on the EGR, fuel filter, cap, rotor, wires and plugs. Have checked everything I can think of, need help

Common for the gasket under the throttle body to leak vacuum and cause stalling. See if it is broken or cracked.
