2000 Pontiac Bonneville Se is Jerking hard
Recently my car started Jerking hard, while driving. I notice it when I am accelerating. It kinds feel as if its sucking up air, and exhaling. It don't do it all the time, and some days a few times a day. I'm not sure if this has anything to do with it, but the ac started messing up. when I turn on the ac for vent, it wont work. when I turn on for feet, it comes out the defrost. then the ac goes up and down without touching. if I put on low, it will go on high, then low, then back high. Few months ago I had the Radiator changed, and spark plugs. I get oil changes regularly...about 6-7 month ago changed the spark plug wires.
