So the problem was there before you changed the clutch and the dual mass flywheel.

I would start from there.

How did that rattle sound? Like something loose? High sound, deep sound?

Bad idling and stalling - some ideas:
Did you check if the engne gets false air?
Did you do a pressure test? I don't mean compression, i mean if the system looses underpressure.
Did you check the MAF? Is it clean? Does the throttle valve closeses 100%? So no gaps, or bearing play?
Did you check the timing - especially of the camshafts? Because if a chain is jumped over you'll have a bad timing, which can cause a bad idling, but also a good runiing engine at higher rpms. But in the end you'll get a bad engine fail.
Did you check ignition coils?
Did you check the O2 sensors?
