AC draws about 2 HP when full on so if the engine is incapable of generating at least that much when at idle , it stalls. The problem is in the ECM - either it's badly calibrated or there's a fault in one of the sensors. You need to have the codes read / checked for a precise diagnostic.

My 2005 envoy stalls when you turn the ac can keep it running if you give it gas.

The throttle body needs to be cleaned, grime in this area prevents the throttle plate from closing completely and allowing air to enter, making the air/fuel mixture lean.

Throttle body needs cleaning, build up of grime prevents butterfly from closing completely. Make sure to disconnect battery for at least 30 minutes while cleaning TB, this will allow PCM to relearn to cleaned TB.
