I've been having a morning start-up problem where my Fit stumbles before it catches and runs, but it only does this on the very first start in the morning. It's a kind of ragged start for the first few seconds and then it's OK for the rest of the day.

It almost seems as if a cylinder has gotten excess fuel in it, and makes me think do I have a leaking injector which seeps in after an overnight shutdown? Just had valves adjusted and new plugs done 3 weeks ago at the dealer.
