Sounds like it's running rough when cold. Plugs, coils, valve adjustment, oil change...
What's your mileage and where are you on those things?
Plugs were done, i'm familiar with the coil stutter, this doesn't seem to be the case. I've done valve adjust on other FIT and planning to do the same on this. Getting about 38 mpg.
Some searching, I was thinking about cleaning Idle Air Control Valve.
