2003 s10 blazer will not idle but runs great when foot on the gas pedal

Question

I have a 2003 s10 chevy blazer that will run great when started and is cold. But once the engine warms up the the engine will stall.you can restart the vehicle but you have to put your foot on the gas pedal and give It a little gas to keep it running. It has pulled many codes and I have fixed all the problems the codes has said. I have replaced all plugs, plug wires, rotor button, and distributor cap. Also replaced the crank shaft sensor and none of this has fixed the issue! Can anyone please help me? This blazer has the vortec v6

Hi there

Without knowing what all the codes and the work that has been done,I suggest checking the IAC. Remove it and clean it up. It could be gummed up and not working properly. I would also check for vacuum leaks. This can cause the engine to shut down at idle.
