The problem is that when the Air conditioning is turned the car shuts off or starts to vibrate. Its not instantaneous, and if you keep the revs above around 1000 it will stay on, but if you stop at a light or something the idle drops so low the car shuts off. Of note as well there seems to be a rhythmic tick comes that goes away at RPMs above 1500 or so.
Vehicle is Cherolet Joy 2006.
