Pay attention to the cylinder adaptation values. These relate to how well the computer is managing to keep the air/fuel mixture close to the ideal 14.7:1 ratio. It uses the input from the MAF and O2 sensors to adjust the fuel supply to the cylinders. I have attached a useful document on adaptation. It may help in diagnosing which cylinders are faulting.
