Cry Like A Baby 156 Sportwagon 1.8TS (Tick over Problem)

Iv a Problem that I'm hoping someone can shine some light on.. Iv a 2000 plate 156 Sportwagon 1.8TS.. When its stood ticking over it sits at about 600-1000 rpm.. just lately however its fluctuating between 1100 through to about 400rpm (up and down) sometimes hitting about 300rpm and stalling. Also when it dips to 300rpm the dash lights dim and brighten as it goes back through to 1000rpm. The problem also occurs if I'm coming to lights and while coasting at about 10mph take it out of gear the revs drop and stall if it hits 300rpm. I think the problem lies in the fact that its fluctuating between 1000 and 300 (dipping out). When I'm driving there's no power loss through accelerating, its still very pokey. Has anyone had this problem or know what could be the cause?? I had a similar problem with another car and i just turned up the idle speed but iv not owned a Alfa before..
Oh yeah had the cam belt changed last year don't know if that makes any difference ?
I appreciate its a long question
Many thanks

Sorry Matt,it's not,it is the idle actuator which causes that, almost always on cf2 TS's.

I have a 1.8 TS 156, and the symptoms are similar... The car doesn't stall, but if I engage the clutch while it's moving, the revs begin to bounce between 500 and 1200 (aprox...).
If I'm waiting in the top of a slope, and suddenly I stop braking, the car begins to move (it begins to tick over). Then, the revs also begin to bounce, and they only return to their usual behaviour if I do one of these things:
- I stop the car (braking).
- I engage a gear.

I went to my Alfa dealer and to other garages... Nobody knows why my car are doing that!!

I thougth about MAF or idle actuator, but they said that it's perfect... I don't know...

I'm with AT for both of you on that. The car stops doing it because ther is less load on the engine because the clutch is engaged meaning less rotating mass, hiding the problem.

Was the problem fixed?

I'm having the same problem, after having removed/reinserted all relays in the engine bay.
With the addition of the Injector Warning Light staying on...
