Gas Cap problem

[AnsteyZ71]

Hey Guys,
My check engine light comes on about once a week because of my gas cap. I think it vibrates lose every so often. I've been tightening it every other day but if I forget there goes the light. Does anyone know of a fix or should I just replace it?

They are cheap, so I would just replace it. My .02

I would to just buy one from dealer, so they can't say ..oh thats an after market, we'd love to help you but.

How long have you had the truck? Warranty replacement?

I haven't had any problems yet, but will keep my eye out! Thanks for the heads up...

I had it happen once on an 05 Colorado I had. Ended up doing the "disconnect the battery to reset the computer" fix.
