I took the car out and did some monitor reset type driving, and it got way better, but still has a light miss at light throttle. On hard acceleration, there is no discernible fade, hesitation, or miss. Old plugs looked very healthy besides wide gaps due to normal wear. There were none of these behaviors before the change. It was running great, but due for a freshen up. Ideas?
