I have a Ford Contour 98, 4 cylinders, standard, and its problem is that the engine is unstable and stalls. The battery does not charge properly and the Check turns on. A tuning has just been made but I still do not know why it keeps failing.
Maybe but not necessarily. Mine the alt. Was replaced...still did the same thing as described by person asking questions. Never figured it out. Had erratic voltage. Wired a volt meter inside cab. Watch volts go from 8 to 24...that was with battery and alternator replaced
