I've got a 91 Altima with 120K on it. Today the "Service Engine" light came on. I also found out today I have to be in Mississippi Friday morning. Can I drive this from Illinois to Mississippi and back without worrying the car will die on some lonely stretch of road!? Will any damage be done to the engine? I can't get the car into the dealer or a mechanic until Friday and I HAVE to be in Mississippi Friday morning for sure!
