2008 S80 T6 Hard To Start, Solved!
 

My 2008 S80 T6 was getting very hard to start sometimes taking more than 5 tries to get her running.
I solved this issue by cleaning the throttle body.
I removed the plastic intake manifold with the throttle body still attached, flipped it over and used throttle body cleaner and a rag to get all the gunk out.

She starts fine now! :)
