Be gentle... I am kinda a newb.... but I have a 16 FiST with Whoosh Hybrid and Cobb Stage 3.... i kept getting the stupid code. I saw other guys said converting to the 2014-2015 EVAP hose/setup thing fixed it. I spent ... i forgot... 150ish or so? Ford OEM part. It has been months.... no issue. Cobb was like... "Have you performed a smoke test?" pffft. Of course I did. Anyways.... I know it's frustrating. I hope you guys get it figured out.
