]Hey there, I was doing a valve adjustment and leakdown test and noticed my cyl 3 and 4 spark plugs are darker than 1 and 2.. Engine is a h23 VTEC ,and honestly I never noticed before lol..
Only thing is reading might be false since I only ran the engine for about 30min mostly idle , less than 2k rpm , freshly out of winterizing..

Any clue if I'm having serious issues?

all the fuel injectors are fed the same rail pressure and regulated the same. so only other thing it could be is dirty/ faulty injectors.

or maybe just a incomplete burn due to ignition source.

id rotate the injectors ( label the suspected faulty ones with a paint mark dot)
also throw in fresh plugs and check again in a few months

I will recheck my spark plugs in a few weeks when I really run the car and with fresh fuel!!
