Erractic Idling

With my 850 (10 valves) I understand that there's no way I could
adjust the idling device (or non in 10 valves model) as in 20 valves. Sometimes ,I felt there is some erractic idling while at traffic lights.

Is that normal?

Idle is controlled by the ECU in all of the 850's. The most common cause for erratic idle, especially on the non-turbo cars, is a dirty throttle body and/or dirty idle air control valve.
