So the car developed hesitations during aggressive pulls. It would jerk as if losing power for a split sec, Misfired over and over especially over 3k rpm, while cruising and then mashing the throttle it was most prevalent. Data logs showed all good info except misfires in 3rd gear on 3 of the logs.
While driving and overtaking yesterday the car must have had successive misfires and shut down cylinder 4 completely. Lost power and car went into limp mode.
Today was able to get plugs swapped, which solved the issue as of now, but I had to order coils too as a few of the existing ones looked off. Coils, tranny flush, diff flush and TC flush coming next week.
