I've got a bit over 108k miles on my 2017 Tahoe and am throwing my first code, ever. I did some searching and it could be the evaporator purge valve which is an easy fix but rather than throw parts at it, I see that the fuel neck does not look as though it is closing completely. Could this be the culprit?
