I have about 40k on wrx currently running cobb stage 2 93 octane I had the code pop up once, and reset the ecu and it has been good since, Think it's time for new plugs?
It's so minor it's not even right. I do Body work for a living and it would only a skim coat of filler to repair it, I could even help ruff it out.
