Hi,
At stop, idling speed is around 750rpm if I leave gear in "D" but the SUV wants to move forward.
If I shift gear to "N" a few seconds after the full stop, I can feel a bump and rpm moves up around 1200 before moving down back to 750.
It can be a vacuum-pump issue, per one of my friends ...

Hi,
One of my volvos (2005 XC90 V8) started having the same problem.
I am also shifting to N at stop.
Did you find a solution?
I am planing to take this old one to my dealer if I cannot solve it soon.
Thank you
