Was this a flood recovered vehicle if so you'll have alot of problems with the electrical system mainly corrosion inside the computer. If not than you probably have a pretty simple fix. Your coolent temp. Sensor that relays information to the computer(not the dummy light or fan control sensor) regulates the air fuel mixture according to engine temp. If this is not working it will show the vehicle as running cold all the time and will create a rich burn and will trigger a o2 sensor problem code, more so will actually burn out the o2 sensors one after the other. Also this problem is typical for dropping fuel economy
