An interesting idea about the injectors, I've not really considered them as there's been no cylinder-specific codes. Think it's unlikely more than one would fail at once.
Me too - to be honest it sounds like air getting in the manifold until the engine warms up and seals the gap, but you have checked that out.

As for a Colourtune plug they can be really useful, as you can see inside each cylinder and check whether you are getting a spark, and if so, running rich or lean.
