Getting over rich on bank 1. Live data showed -4 to -5 long term on bank 1 but bank 2 was 0 to +1. On urgent acceleration, short term 1 would go to max, accel limiting came on w/eng light.

I guessed one or 2 injectors were at fault so I swapped 1 and 2 banks. cleaned the seals and spayed out the input side with brake cleaner, siliconed the seals.

To my surprise, the problem did not switch sides, but it did get a little better: -3 to -4 long term on 1 and +1 on 2. Stomping it did not throw and error and did not get to rpm limiting. I didn't reve too far since i wasn't happy with the -3 to -4.

So what should I try next?
