Also, how long was your car running to get those misfires? those are not a lot of misfires.

I would not guess bad O2 sensors in your case. Do you have any vehicle modifications? What octane fuel do you use? Have you tried fuel system cleaner? (royal purple complete fuel system)

The GT (US version) (30k Km) is completely stock apart of a leftside catchcan. Fuel / injectorcleaner is applied, sparkplugs all renewed and only Shell Vpower EU 98 (5% ethanol or less) is used. The shop noticed during a life scan indeed some misfires on cilinder 3 and 6. My next step is renew that nr. 3 and 6 coils.

A10 or M6? If A10, try relearning the transmission - free and maybe trying to shift between gears and not be a misfire issue. Just thoughts

10 speed automatic. Gearbox Table reset once done by disconnect battery for 15 min, no difference. Hopefully not manifold issues.

OP, ever figure this out?

Had the same thing, mainly between 2-3k rpm. Ended up getting a new engine 2 weeks ago because 3 cylinders were down on compression and had scoring. Always changed oil at 5k, warmed it up etc.

I spent 2 months chasing it, replacing plugs, coils, DI injectors, port injectors, checking for air leaks...
