I was driving my car today and ran over a pot hole. I think it may have knocked something loose in the engine or the transmission. A new engine was put in the car im not sure of how long ago . When I came to a complete stop the car had shut off on me and the gas light and battery light and emergency break light had came on along with another light but I forgot which light. The car will start but will not stay running. I have tried to pump the gas pedal while the car is running and it will run but inly for a few seconds and is very weak. I had jus put 30 dollars of gas in the car that morning and also put more in the car thinking that could have been the problem. Any type of advice would be greatly appreciated. Thank you, Christine..
