Not yet. I did recalibrate the o2 sensors and swapped sides. They still showed cylinders 4-5-6 as about .5 point richer. I rebalance the itb’s, including up at 3,600 rpm (my airflow gauge was maxed out by the air volume at 4000 rpm). I checked torque on the intake and exhaust manifolds. All that and the discrepancy was still there.
Next up is to swap sides with the injectors to see if that is where the imbalance is.
