The O2's are pretty sensitive. If your originals were fine, removed, and re-installed, that alone could have damaged one.

My problem was a bad heater wire on the sensor after removal and re-install for headers. The O2 couldn't heat up enough to get out of the warm-up cycle. The result was mpg like yours and an intermittent stumble at idle.

Weirdly, it didn't happen right away -- it got gradually worse over time -- and other than the mileage and occasional stumble, it ran fine.

If you have a buddy at Nissan, ask him to hook up Consult III and monitor the O2 voltages, heater corrections, etc to make sure all is good.

Good luck!
