Hey everyone so I just bought this car and I have already had to replace multiple parts in it, but one problem still comes up. When ever I turn my air conditioner on and I come to a red light the car shuts down. I checked my short ram intake for a possible vacuum leak, but I did not catch anything. When ever the air conditioner is off it runs fine, but its hot as heck and I need that. Any ideas as to what it could be? When I stop at a light the rpm's drop to about 1000 then it shakes really bad and cuts off. The only way to keep it on at a light is to put it in neutral and it stays on. Little help please.

First eliminate all vacuum or air leaks in the system (very important)

. You may have a bad IAC ( idle air control) but try cleaning the throttle body first. Remove the intake snorkel, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carburetor cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still has a problem, replace the IAC.
