    The Check Engine light remains on constantly. My mechanic is baffled as to why this is occurring.

    When I bought my car, I bought a locking gas cap. When I took my car to get it fixed, the guy told me to try the old gas cap and the check engine light went off.

    2003 Buick Century code P0442. Evap system (small leak). Bought replacement fuel cap from GM (I read that it must be from GM). No "service engine light" after 50 miles.

    NEVER overfill your gas tank. When filling up and the gas hose clicks off at the pump DO NOT fill to max. Also Make sure the gas cap is tight after filling so as not to create a vaccum. Common sense fixes this problem.

    I had to have the gas cap replaced because the light kept coming on and once the cap was changed no more problems.

    Tightening gas cap 4 clicks avoids the problem. Replacing the cap solved it.
