When I was reading your original post it made me think fuel pressure. I had a crappy adj fuel pressure reg on my 940 and that would make the car hesitate when accelerating at certain revs. It would also run ok at high revs as i guess it was injecting alot more fuel although it still would of been lean.

When i say it was hesitant, i was almost like the car was getting blown by strong really quick gusts of wind from the front. like it was accelerating ooo errr ooo errr ooo errr!! (this probably makes absolute no sense!)

At idle it could be very fussy. Shutting the bonnet would sometimes make is want to stale!

I would get a second hand fuel pressure reg and bang that on, you might get for free or you could get a lend of one maybe if you ask on here.
