swap injectors
So I had a jb4 G4 installed on my brothers car. Had misfiring issues. Swapped new plugs in and still had misfire in cylinder 2. So we put in a new coil and everything was great. Not even a couple days later cylinder 2 misfires again and often. So we were thinking injectors and swapped injector 1 with injector 2. No misfires at all. Was just wondering what could've changed? Seems to run great right now.

maybe the injector was seated wrong? Did you code the injector as well?

Never messed with the injectors before. Just swapped them to see if the problem would move cylinders. No coding at all. Weird situation just curious to see what made it work.
