    Default 06 tahoe check engine light on smell gas

    Hello, I'm new to this club.I have an 06 Tahoe. A few weeks ago I had a message on dash to tighten gas cap.It wet out right away. The next day same message then went away after a few minutes before I could tighten cap. Next day the check engine light came on and stayed on.Afew days later I some times can smell gas.Has anyone had this problem?
