I have a 1996 Ford Crown vic and recently my car has been giving me throuble. I can be driving down the street and out of nowhere my car just stops running. Can anyone give me possible answers to what might be the problem?

Check all your battery connections for corrosion and make sure they are not loose. let me know what happens.

A common prob;em with those cars is the plastic and rubber adapter pieces going from the air filter to the throtle body check and make sure they are tight and have no leaks of air if the boot is cracked and sucking air the mass air flow sensor will give erratic signals to the computer and cause the problem you describe
