I had an O2 disconnected (hilbilly at the exhaust shop moved it and never reconnected), and then along the way had a misfire in #8 cylinder... got like 12mpg over half a tank.

If you have a cam in the car that REALLY isnt that bad of gas millage. Depending on your driving it could very well be what the car is getting b/c of the cam and whatnot. If not did you tune the car up... fuel filter, PCV vavle, air filter, exc all these things can have an effect on your gas millage and kill performance
