Just got this car a few days ago from a friend. Here is the problem-he ran onto the shoulder of the road adn the car cut off. Once he cranked it back up it started making a tapping noise from under the hood. He drove the car about 2 miles and parked it. Now the engine seems to be locked up. I gave him the towing fee and he gave me the car. Any ideas of what may have happened or what could be wrong or did I pay thirty dollars for a Contour tool box? I am new to fords so any help would be appreciated.
