engin stops

Your 1998 Ford Taurus may have "lost" its "learned" base idle due to the battery going dead. The first step is to determine why the battery went dead and repair that problem. With the battery in good order, an idle relearn or throttle body cleaning may be necessary to restore the proper idle.
