  • Gas cap throws on Engine Light....purchased an after market cap, light came back on. Problem resolved with a cap ordered from a Chevy Dealer for the exact year, make and model......light never came back on.

    Received several messages about the gas cap being loose. Tightened it every time. Then the Check Engine light came on due to loose gas cap. Took it to the dealer. They replaced the gas cap. Check Engine light came on again about a week later. Dealer replaced a valve in the fuel system. Picking the car up today, so don't know if that will be a permanent fix or not.

    Engine light coming on and every time we take it to dealer the say is faulty gas cap. Replaced and is ok for about a year and then light comes on and cap is loose and will not tighten. I replaced two since purchasing new in 2007. Is there a better cap I can purchase I have always bought from dealer.
