Hi guys, I’ve been having this issue whenever my AC is on and it starts blowing cold air, my RPMs will drop at a point when you can hear that the car is gonna shut down, it doesn't shut down but it sounds like it's about to stall and I don't know where to look at.

You can barely hear the difference in sound but you can see the gauge drop https://youtube.com/shorts/QwqE6UtYzno?feature=share
Above you can see the video. Thanks
 
Any other idle issues besides when the AC is on? Does it idle up on a cold start? Does it adjust for electrical load like headlights and rear defroster? Do you have anyway to take/share a data log?

If 2g is like a 1g, it should idle up a bit with the AC on. If I had to guess, your ISC is the culprit - dirty, broken wire, or just malfunctioning.
