Oil weight for bigger injectors?

The dealership put in 15w40 last visit and today was the first "cold" day for truck. right after the cold start, I hopped in and took off but it only had half power and was missing until full op temp then it ran fine. stiction....obviously. i don't really want to yank the injectors and send them off quite yet. would a thinner oil possibly help? I don't want to get too thin because of shearing and too thick would help sticky spool valves. and before anyone says it....yes i know about rev x. what's the ideal/safest weight for larger injectors in this thing? this isn't a cold start issue...just crappy running until warm. 10w?

2005 CC FX4...compounds and everything else that goes with em.
