    Is it connected to the rear of your air box....If yes then it is the purge valve for the Carbon Canister, WHen the car is left the carbon canister absorbs fumes from the fuel tank when started the purge valve empties the fumes into the intake to be burnt...........

    Hope this is of some help...............

    You should be able to hear the valve ticking, as it meters the vapour into the intake manifold on idle.
