There is another one,change it.One is upper bank,then you have lower bank.If it does not fix your problem ,then do a tune up on your car,plugs more than likely.

@Mark - I always like to mention that replacing a sensor only fixes things IF the sensor is bad. All things being equal - the sensor could be detecting that there is an actual problem to fix.[ I'll leave the bank 1,bank 2,bank 97,etc. up to others... my bank is downtown :) ]
