For several months since I've had the car. It will from time to time stall out. Now it crank but won't start up. You can be driving or idle and the car shakes and stalls out. Due to this it caused my car to overheat. My car will crank but not move at all. The other issue since I bought the car it ran hot. So hot to the point that it crack the radiator hose. I replaced. The car would run hot if you sat idle while driving for too long.
