Car: 2012 2SS Camaro L99 - Auto
Aftermarket AEM COI
Last Fill up: 3/25/12 - 3983 miles - Shell, 91

I just threw a code at 4152 miles,

P0442 EvaporativeEmission Control System Leak Detected (small leak)

I’m, fairly new to "new" car's, still stuck in the 80's era of Camaro's where I could just count the flashes of the check engine light blinking with a paper clip... so any help on what this may relate to would be appreciated, its still under warranty - I only have an AEM intake installed, and wanted to make sure this isn't something that GM will find as the cause the check engine light went off if it needs to be taken in, since i know they're good at that (06' Aveo, they blamed a fuel electrical issue on the after market radio which was put in the car prior to me purchasing it, so wasn't covered)

From my understanding, this should be a fuel system vapor "Small" leak? So maybe me pulling my gas cap off and putting it back on could fix it (unlikely)?
