s80 problem: rough running

I am fed up. I am a loyal owner (91 740 wagon, 92 740GLE and Volvo boat
engine and a 2000 S80). My local dealer cannot get my S80 running right.
From 45-60 it runs very rough. They cant find a thing. I am considering
selling the car because of it. Help

 

i have a s80 2,9 1999 - it runs rough when temp meter is halv way, always
has and probably always will?? 3 times in service but no change. Just have
to wait till engine´s hot then it runs really fine.
otherwise really nice car - just lack the twin turbo and automatic gearbox.

 

I'll give an opinion.. let's look at what could be wrong.. some air/fuel
sensor, fuel surges due to fuel pump issues, some computer issue.. about all
I can come up with. I assume the plugs are in good shape and the air cleaner
is clean.

I would assume if the dealer can reproduce the problem from 45-60, they
should be able to fix it. My guess, some air/fuel sensor.
