Hello. I am having a misfire issue on my 2012 civic si. I have swapped ignition coils, misfire stayed. It’s quite audible, only happens under light load like 2000 rpm. My dipstick smells like gasoline, and I ran the codes and found that during the misfire, my ecu was pulling fuel -5% on the Stft. Only mods I have are a catback, aswell as some aftermarket front lights (not headlights just the bulb is led now)

I'd do the one first to see if it solves the problem.
