I have been chasing a P0300 random misfire. So the other day I used the PID list from the Calc.VET. After capturing the log I ran it and noticed the Bank 1 and Bank 2 LTFT were different. It was my understanding Bank 1 was one side of the motor and Bank 2 was the other side. If that is the case I would think they both should be close if not the same. Bank 1 was 14. something and Bank 2 was 11.4 about. This would lead me to believe I have a lean condition going on which might be causing my misfire. Any Ideas?

I have a 03 Silverado LQ4 4L80 4 X 4.
