  • Lean #1 Bank?

    My SES light came on awhile ago, I finally think to take it by Autozone and check it out and the guy said it came on due to a number 1 Bank being too Lean. Has anyone else had this problem? Could it just be my O2 Sensors or is it a spark plug/wire not giving enough spark?

      Alright, Thank you very much, and BTW should I just go ahead and invest in some O2 Sim's or should I go back with the Sensors

        If the O2 sensor in the exhaust manifold is bad, do not use a sim there. An O2 sensor sim is only for the after cat sensor. ;)

          yes, do not use a sim on the front 02's


          Bank one is teh drivers side 02. It's probably the 02 but other things like.. Vacuum leaks, exhaust leaks before the 02, injector problem, low pressure/volume.. the list goes on

              So I should replace just the Drivers side O2 Sensor or should I replace both at the same time? Again thanks for all the advice!
