My Liberty threw a Po456 code on the way home from work today. Very small evap leak. Has anyone experienced this code, looking for a place to start. I know to check the gas cap, I did, it is original. It has been 4-5 days since the last fill up, no code until today. Usually the evic scrolls gas cap if it is loose.

Thanks Dave
