i just got my car out of the shop the other day, i havent really driven the car in over a year. I drove 534 miles in 4 days and i had to fill up my tank 3 1/2 times. average on the computer is about 11.2 miles per gallon.

Any ideas other than oxygen sensors or leaks?

Pull your battery to reset the system to begin with. If that doesn't help you, people have mentioned to run some Techron through your system, and to change gasoline brands. Poor fuel mileage has been contributed to a failing fuel pump, as well.
