the service engine will stay on until the electrical problem it has dected is fixed. to have this checked take your vehicle to a garage or a parts store and have them scan the vehicle this scanner will tell you what the problem is and once fixed the light will go out. Note* you can have them delete all engine codes and light will go out but about a week later if not sooner light will come back on
