    Hissing fuel cap

    I have noticed my fuel cap hissing lately, and have narrowed it down to the breather system.When the car switches over and stsrts pulsing the solenoid the car drops its revs and starts to run poorly for 30 secs or so then clears. I recon the charcol cannister is dodgy, so what i am saying is a) has anyone else had this as a problem and b) does anyone have one i can have etc etc

    Thanks
    Mark

    the fuel system is closed system, and the hissing from the cap maybe due to a worn out fuel cap.

    Yeah that and when the car activates the little solonoid on top of the airbox, the car idles funny for a short time then clears.So i was thinking it wasnt working properly when it swaps to the closed loop, hence a dodgy carbon thingy.

    Sound right????

    but isn't it hissing from the fuel cap? that suggests that it isn't sealing correctly.

    Yeah, but my thoughts are if its hissing there, it isnt breathing properly through the rest of the system ????? As the seal etc looks intact and i always click it yp when doing it up
