MY 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.

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