Please help me locate idle mixture screw/s on 2006 Volvo 3.0 GLP-D.

I can find the idle screen no problem but i really to adjust the mixture....I think. I can't seem to locate it. It does not show the location in the manual.
Whenever I shift into gear, the engine will stall unless I gun the throttle. Also, I frequently get dieseling when i turn off the motor. I already checked fuel line/filter and it seems fine.
Can somebody please describe where the mixture screw is located! Thanks in advance!
