The bosch really do not work. I chased a very lean problem for about a year after I had switched to the Bosch splice in sensor. Finally, fixed it with switching back to the OEM Denso brand 02 sensor. The bosch sensor sticks down into exhaust pipe only 1/4" while the OEM sticks down almost 3/4". No way that Bosch unit can get a good reading.
