: Gas cap.

04-13-11, 12:39 PM
Lately I've been getting a "tighten gas cap" message on my DIC. I've tightend it a few times but it keeps coming on again. I know it's tight. I'm wondering, do I need a new cap?

I had a similar issue with one of my other trucks. The 'Service Engine Soon' light kept popping up. My mechanic scanned the onboard computer and told me it would be a simple fix. I changed the gas cap and SES light went out for good. Just do it.

Yeah my SES light came on a day or so later as well....Thanks, I'll give it a try.

As said change the gas cap, both of my 10's had to be replaced for the SES light :(
