mystery cough?

Hi guys I was wondering if anyone would know why my Xflow, after sitting idling for four or five minutes develops a miss(sorta more of a cough) once you take off agian and doesnt go away till you give her a bit of a run, its got a GT head, 32/36, ghia air cleaner and pacemakers. Any other time she runs perfect with no dramas.
 
Cheers
Brad

    May be a leak somewhere.  Check all the hoses and manifold face as well.
     
    May also need a tune.

    Hows the idle mix. Are the plugs fouling on idling for a while?
    Vacuum/Emission hose leaking?
    All i can think of if it only does it after idling a while.

    OK thanks heaps guys, also I forgot to say she has a lumpy cam but no matter. I did look(listen) for leaks and  checked the plugs I do think I could turn the idle up another 100rpm or so, I know its not a major issue really but you never know what it could grow into. I might just have to blow a few bucks and get a pro to give her a good tune for me.
     
     
    P.s Anyone know if there are any GOOD dyno tuners in the central west NSW ie Orange,Dubbo,Bathurst?

    Could be a list of things most of which are mentioned above,
    mine didnt like idleing for long and problem was rich mixture.
    Be careful upping the idle speed Xflows tend to run on after key is off due to high idle setting. Get it checked asap.
