    Hi All
    First of all my van runs great, no smoke, nothing untoward.
    My issue is this, when i start the vehicle cold hot or anytime the engine sounds a bit rough? but after a few seconds the idle speeds up a few hundred revs and engine is much quieter?
    I have also notices that when it is started before it goes quiet, pressing the throttle does nothing? but revs as normal when idle increases.
    Any ideas??????
