So I've ebcame the latest person affected by the #3 Cylinder misfire and oil consumption issues. My Accord has 70k on it. Mostly highway miles. On Wednesday I got the flashing MIL light. Turned the car off in the driveway, checked the sparkplugs and saw the #3 Cylinder plug was fouled. I had a spare plug so I installed it. No more misfire.
I took it to honda anyway along with the bad plug. I got a call friday morning that there was a TSB for the PCM update and that they were going to do that. They also replaced the plug with a new one for free. They said honda is aware of the oil consumption and fouled plug issue as they go hand in hand. I was told to check on my oil level for the next 6k miles. If I am short on oil, they will take the car in and do whatever needs to be done. Service manager said it could be new valve seals or a complete new shortblock. He said my issue is likely to return but for now he had to follow protocall.
What exactly the PCM update takes care of, I don;t know but was told it was related to the VCM system and it almost always happens in Cylinder #3
