Not heard of this problem before ......
Firstly, I'd try changing the fuel filter, and filling the replacement filter with Diesel Magic or Forte before refitting it.
It might just clear any gremlins from the system, and certainly won't do any harm.
See how you go from there.

Have you checked that your ICV (Idle Control Valve) is all connected, with leads in place and it fully pushed into the plenium? :-? :-?

And they do not have an ICV??!! :o :o :o :o :o Wow, you always learn something new every day, but I have not worked on a diesel ever!! ::)
What controls the idling speed then? :-?
-
I think that idle speed is controlled by the fuel temp sensor, (in the injection pump), and 'start of injection' sensor, (within No.4 injector).
Maybe I'm wrong ?!?
Omegatoy and TheBoy will hopefully be along soon to offer guidance!
