I just swapped out my O2 sensor after having a bout of poor mileage (23 100%
highway) and pulling codes (confirmed O2 probalem). I had replaced it 5
months back with a general tune up, but after I replaced all vacuum lines
and other gremlins, I assume I fouled it. IN went the new and my mileage
barely went up .5 MPG, again all highway. Is there a breakin period for
O2's? My first tank or 2 with the car I did get 27+. I also get 27 on my
other avant wth twice the total miles. No mods etc, same gas. Oil smells
more like gas than I would like and oil consumption was up a bit. I assume
I was/am running somewhat rich and cutting the oil a bit with too much gas,
Any BTDT's welcome.
