Any suggestions? It came on a day after we put gas in it. Car has been started approx 10 times since light came on.
My gas cap light came on then the next day the engine light came on. on 2006 Mercury Mountaineer
you may have a vac leak in evap system,get a smoke test done if gas cap does not fix issue
