I was driving down the highway leaving the barbershop and my car wouldnt go over more than like 55 mph and I got a flashing green symbol beside my check engine light which had just came on when the AUTO (Stop/Start) light did. once I got home turned it off and turned it back on the for a second the light doesnat come on but once you drive it maybe a quarter of a mile or less it come back on and the car wont function properly again
