I'm having a small issue of my CEL w/ the code p0455 not clearing off my dash even with my tuner. Tuner said codes were clear and the CEL didn't turn off. Somebody know or have had the same issue before? I never have.

 

Do you know where the EVAP leak is coming from?

 

no, but reset pcm by disconnecting neg battery cable and turning on headlights for 30 seconds. when i had an evap leak it would take about 2-3 days for it to come back on.

I really haven't had the time or a decent place to look at where the leak could be coming from. When I bought my truck tho and ever since then the gas cap hasn't been reading right like it isn't on tight enough. And dvaughn thanks for the link, i've looked over it before but when it warms up I'll most look at the hoses and replace them if needed.
