Hi
What can cause lean fuel condition by 24% in bank 1 ( driver side ) compared to bank 2 ? the car is f body with 416 engine , ls3 injectors , SD open loop tune. The fuel injectors and rail were checked and replaced but the condition did not change. All cylinders are firing ( checked with IR heat gun ) and LTFT STFT are 0% .
