happened again on the way home from work, car sounded like a V-twin sport bike for 10 miles lol. used the data loggers diagnose feature to determine it was the number 2 injector. pulled over and un-plugged and plugged in the plug a bunch of times to work the contacts clean. Car drove the rest of the 20miles home just fine. I think we know the culprit. also the contacts themselves have green corrosion on them.
