Gearbox and idle acting odd in the cold

Yeah, I saw that one on the right hand side on some of the pics I was looking at. I suspect it does the same thing, but i'm not sure why UK\US cars would have two whereas Jap spec would only have one; nothing logical springs to mind.

So where it's placed and what it's buffering means it would be doing the job I described, so just check when you open the throttle plate, like your doing in the picture, that the piston extends a bit, probably about 5mm or so and then when you let the throttle go it should snap back round but the last few mm should be buffered by that piston.
