Had terrible fuel mileage as I posted previously. Had a "used" O2 sensor installed after the 1st CAT and my fuel econony is back to where it should be according to fueleconomy.gov. Just got 28.7 MPG mixed city/hwy. So for those whove changed plugs, fuel filter, air filter, etc. and still geting bad fuel economy, could be your O2 sensor.

It was the 2nd one "back of the cat", even though our cars have 2 cats. Both can be replaced by you with a few simple tools. The bad thing is that the OE O2 sensors aren't cheap. Or you can splice into your existing wiring and save some cash using "universal type"
