2009 Pontiac Vibe 1.8l 2ZR-FE stalling when turning on AC on full

Hello Folks…hope you can help.
My daughters Pontiac Vibe stalls when in drive or reverse when the AC is on max. In park it is fine. Parts that have been replaced recently: Rad and fan, coils and plugs, fuel injectors, ignition switch, MAF sensor and air filter and PCV valve. I cleaned the throttle body 3 times and did the idle relearn. There is no IAC to clean or replace. I checked for vacuum leaks and didn’t find any. Alternator puts out 13.34 volts at idle. I’m at a dead end….any help would be appreciated. Thank you.
