Rpm drops to 250 with a\c on when coming to a stop
As title states, with a\c on will be driving with say rpms around 2500 , when slowing down, to a stop rpms will drop to 250, engine starts to shake like it wants to die, for say a second then will climb back up to 750 rpms ... only with a\c on... any ideas??
