Rough idle at stop 2004 volvo xc90 t60 Topic is solved

Hi all, experienced a rough idle at stop lights today after driving over an hour. No check engine light, seems fine when driving on the highway, maybe a slight loss of power. Is there an idle control valve or something that typically needs clean or change on the 6 cylinder xc90? Will start with spark plugs but there is no misfire code yet

I don't know much about 6-cyl model, but in my 2005 XC90 2.5T, I cleaned the Throttle Body.
No longer has idle issues.
I wrote a DIY Throttle Body Cleaning in this forum a few yrs ago.
You can search for it, and perhaps update that thread with your experience with 6-cyl engine.
