[s-cars] crazy fuel gauge

[serge]

I get about @16 MPG in the city (Brooklyn stop'n go) and @20MPG on highway
trips to Ohio (2 small kids + wife +lots of luggage). I notice a slight
increase in highway MPG after replacing BPV and Michelin man hose. Car has
MTM turbo chip, IA timing chip and 3 bar sensor, K&N panel filter, otherwise
stock. I am hoping to see better highway MPG after I replace O2 sensor and
exhaust.
