Fuel delivery issue 2 cylinders

For some strange reason I am having two cylinders run lean and two run rich specifically 1-3 lean, 2-4 rich. I have tried new coilpacks, and just recently went back to stock injectors. I even tried a different wiring harness for the fuel injectors. This problem is really weird, could it possibly be a megasquirt issue?

More data. What injectors? Were they flow tested? How do you know that you are rich / lean on a cylinder-specific basis? Idle, part throttle, full throttle? Did the problem occur with the non-stock, or the stock injectors? What Megasquirt? Post your tune. What car? What Mods?
