Rough idle on 406 with 2.1TD Engine

    My 2.1TD 1998 406 starts instantly and runs smoothly when it's dry and even
    when it's freezing (new glow plugs), but after driving a few minutes and the
    engine not quite hot yet it starts to idle rough.
    i.e. when stop at a set of light half a mile away. When it's wet it idles
    slightly rough straight away. When the enigine is nice and hot, after 20
    minutes of driving etc the idle is nice and smooth.
    Any ideas?
