Hiya guys, I have recently brought a Veccy 2.2 Direct and I get a misfire when around 2-3K revs in 3rd gear but only if its really cold outside, I can get up on a normal mild morning and no problems at all! Have changed the plugs so far with no advantage.

Has anybody come across this before?

I found One article about this here but no resolution.
