I started having this problem the other day. Drove to lunch fine but when I left the car wanted to die on me when I was at an idle or at very low speed. And now I can't keep it running long enough to go anywhere. I just had my 120k tune-up about 10k ago. Any ideas what this could be?

Thanks

Kinda' sounds like what I had a few months ago. Ended up being the Mass airflow sensor. Fuel pump maybe? Sorry but this could be a number of things.

We had a similar problem with our '93 850 with 110K mi. Check the torque arm bushing - the little rubber
bushing in the arm over the engine that keeps it from rocking forward and backward. Ours was shot and
apparently the rocking back and forth (upon braking/acceleration) split holes in both the vacuum hose and
the big air intake hose (not sure what it's called exactly) between air filter and throttle body.

The car would run fine in upper rpms, but run rough and die on return to idle rpm. It also had trouble
starting.

both the bushing and the hose repairs were easy do-it-yourselfer fixes, but the old bushing had to be cut
with a Sawzall before it would come loose. Replace the bushing with polyurethane from your favorite parts
source (Trollhatten, IPD, etc.) as the OEM bushing is inadequate.

Hope this helps.

Check all your vaccum connection making it not coming lost or crack..

go to www.volvospeed.com it show some detail pictures where all the vaccum are ...

Vaccuum leak, maybe? Could just be a hose off? I'm no mechanic. Best wishes.
