my check engine light came on while i was driving in town.I did notice that the low gas indicator came on first,then when i got to gas station i notice that the gas cap was loose.What could i do to get this light to go out?Is this a problem that could cause my vehicle to stall on me while driving long distance?What could be the worst that could happen if i keep driving the car with the check engine light on?
