I have a 96 v6 mustang, when I turn on my a/c my car becomes sooo sluggish and slow and chugs gas, it jerks a lot between shifts and especially getting into first gear, I don't know why this happens but I don't like it if there was a way to fix these could someone please tell me!? The car is basically stock. It's about 100 degrees outside and not turning on the ac dosnt sound too reasonable
