Also need to log with your Procede to ensure you don't need to change the OL fuel value. It starts at 75 and can be scaled up to 100 if needed. Log Fuel Trim to see whether the trims are working at all, and if so, they need to stay in the positive range, anywhere from +10% up to +30%. If they peg at full +34%, then increase the OL Fuel value by increments of 5 and log again.

But even so, if you have more than 50k miles on the sensors, then I'd change them anyway. Bosch 17098 can be used in both banks 1+2 pre-cat, just make sure you label them and plug into the proper connectors under the engine cover. Find them online cheaper than any dealer price, and the bank 2 17102 is much more expensive, only difference is the shorter wire.
