I'm having the same issue right now. Hope to have it in this week for a diagnosis. My ODB scanner says P0455 (Large EVAP leak). I'll let you know what my results are.

Welcome guys!

There is a $30 valve located near the fuel filler. One screw and a vacuum line IIRC. As easy to change out as an oil filter.

Search the code in this forum to get the details.
