    Hey guys tune me into which 02 sensor affects fuel mileage. I've got a '96 Taco 4x4 SR5 and have done a recent tune up covering most everything including plugs and wires, fuel and air filters, maf and tb cleaning. 140k and no faults and O2 has never been changed. I read somewhere a while back someone had the same mpg drop and changed O2 sen. and it jumped back up. So I'm hoping that's it. Thanks in advance :burnrubber:
