That is, as long as the correct cylinder is reported to be misfiring. ...but it's one of your direct injectors.


edit: ...or the signal/power to that injector.
I think it was the coilpacks. I swapped back to OEM and did not get cold start misfires, but I didn't get a chance to log. Also drove around and tried to get it to misfire by giving it 50% load at 3k rpm, which usually starts to misfire, but did not get anything. It usually misfires cylinder #4 this way.

Didn't get a chance to log during cold start after swap, but so far signs are good.
