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. .
