Check the evaporative system for a small leak. This is best done with a smoke machine that fills the evap system with smoke, then look for the leak. These leaks can be very small so this is the easiest way. Also make sure the gas cap is sealing properly.

check the rear evap lines to the canister. the metal lines rust and in return crack the hoses. some what easy fix.
