Check mpg again. Has to be more than 10.
ANSWER by on December 07, 2012
Was check engine light on BEFORE replacing all 4 O2 sensors? ...So if you fill-up the tank and drive 100 miles and hit the next gas station you'll be able to put in 10 gallons of gas? Your one reply states that you are not a mechanic so that makes me curious as to who and why the oxygen sensors were replaced, because if all 4 were failed at the same time it would be odd and most likely due to some other cause/failure.
