As for the wierd smell from your vents, I doubt that has anything to do with your gas mileage. You may want to address that in another thread. But be a bit more specific about when it happens and whether the occurances are random or happen when you have the heat or A/C on, etc.
O2 sensor... Like Vital says, it would help us to help you if you would go to the top of the page, click on "Profile" and put your car'* year and trim level in a signature line. That having been said, and since I haven't read all your other posts:
What is your mileage?
How long have you personally had this car?
And what mechanically have you done to the car, if anything?
