    Intake leak, AIR system, fuel pressure/pump, injector(s), EVAP canister, purge valve, H02S.

    Is what my systems telling me. I doubt its the Evap canister.
    Fuel pressure (is your car cutting out)?
    Air system (Are you sure theres only 1 fault code)?
    Intake leak (check hoses for air/fuel system is connected correctly and there is no corrosion?)

    Whats the symptoms? When does it happen?
    Its a jam thing

    well ive been having big trouble with the car, and only just got the trouble down to this fault. when i start the car it idles really rough for about 30 secs then cuts out, like the fuel isnt getting through.

    You need to get the fuel pressure tested to make sure you pump is doing its job. It should be at 3.8 bar.
    Then as a matter of course a new fuel filter wouldn't hurt.
    Check the fuel pressure relay.
    Check the purge valve for Evap canister. (you could of easily knocked this if you've done the air box mod.
    Its a jam thing
