high constant engine idle
My car has been idling high for a long time. It goes up to 40mph without stepping on the gas peddle at all. Now it started overheating. I just replaced the water pump and thermostat. I know that I have a small crack in my radiator, but that has not effected the overheating so far. The other week I was driving to pick up from the airport. I noticed that my car was overheating a little bit, but thats normal for it. When I stopped to pay the toll my car shut itself off. We were able to get it started but when I came to a stop again it shut off once more. When I got the car home (after being towed) we noticed that the thermostat was broken into 4 pieces so that was replaced. Unfortunatley that did not fix my overheating problems, it still overheats almost immediatley after being turned on. please help!
