    Threw code P0442-emission leak

    Hey I was driving home for work and I saw the light come on. My AP said it is P0442 and the manual calls it an "evaporative emission control system leak detected".

    Im not sure what this is or what causes it. When I had my exhaust put on about three weeks ago I used the same gaskets and I am not sure if that could be the problem. I also felt like I heard the spooling much louder than usual this morning and I dont know if that is a leak. Any and all help is appreciated. Thanks

    yea...its definatly not the gas cap...if only it was that easy. The code comes up all the time no matter what I do. I automatically tighten the gas cap about 8 - 10 clicks every time i fill up....thanks for the response though
