Have this car it has about 126K on it. Runs great. Began getting bad gas mileage in town like 14mpg. Chk engine light came on and it was an O2 sensor. I have replaced this and no more check engine light.
Problem - city mpg is still at about 14. This car should be getting like 24-26mpg in the city. Any suggestions as to where to start. HWY mileage is still in the 30's so I am stumped as to what would cause one to dive while the other is still great?
