if you're on power Fc, then you need to adjust one portion which related to a/c fuel cut.
if you're not.. like joewe kong says... tps... and also u might wanna adjust the wax rod that extends out when you throttle and off throttle that will prevent your throttle to drop immediately to low RPM causing ur car cannot idle..
Bump: bear in mind that sometimes these issues can be as simple as battery voltage low...
air con is electronics...so.. start with your basic electronic maintenance... like any loose cables... battery voltage.. etc..then only start going in deeper to idling systems or power fc...
Yes, one of the solution is check the car battery, expecially the -ve cable, clean the shit on both battery head, and try again. make sure you SCREW the battery cable bolt TIGHT TIGHT.
