Malfunction Indicator Light On. Checked For Loose Gas Cap And Put Gas In Truck. Service Said Ride For A Few Miles To Reset Same. It Did Reset And Camre Back On. Any Thoughts On Same.

Might be a bad gas cap the rubber seal worn/cracked prob it.

Since it reset, that's probably what the problem is and you lucked out...

How do you know the light didn't come on for another reason? Did you check the codes?

If it is indeed the gas cap giving you problems, that's what should be replaced...

Thanks for the response. I called the dealer and made a appointment to have it checked out. I'll get back to you when done.
