I am barely getting 15 mpg. I just replaced my 02 sensor and my air filter. My plugs are new. I tested the wires and they are good. The exhaust and cat are brand new. Is there anything I am overlooking that could be affecting my gas mileage? Or should i just expect this from a 12 year old car with 190k miles on it? Thanks for any help guys.

Logic would seem to point you towards the components that control fuel delivery. A friend of mine had an old Accord that had a problem with it's fuel injectors "drooling" fuel all the time, even when the valves were closed. That and a hole in his gas tank made for some god awful milage.

Try replacing the charcoal filter element. I have 185,000 miles and still get mid-upper 20's mpg. Driving style affects mileage a lot too.
