    Check your gas cap. If it's a locking type, many of those have trouble sealing. Mine is doing fine, but many complain about it.

    as stated above, start with the gas cap. if you still get the same DTC or any other evaporative emission leak DTC, closely inspect all related hoses and tubes. the hoses tend to crack where they get stretched to fit over tubes or component nipples.


    hehehe, i said nipples.
