With everything I read on the system of the Pathfinder, I found out the Mass airflow sensor was what was tripping the signal. I don't know why it only triped as the right bank was running lean. But it did. I would have thought that the left and right bank would have run lean if the mass airflow sensor was at fault, but it didn't. The test's on the sensor didn't indicate it being faulty. I guess the falt was Intermittent. Anyway the problum is solved.
Thank you for the posting.
