Answers :

Replace the Oxygen sensors, your fuel economy will increase 40% after a new one is installed. Check your tire pressure, replace your air filter, roll down the windows instead of using the A/C, avoid jack rabbit starts, and do the speed limit on the road.

Some things that would contribute to poor fuel economy.

Dirty Air Filter
Dirty MAF
Dirty IAC
Dirty ERG
Underinflated Tires
Mis-Aligned Tires
Worn/bad wheel bearings
Bad Gas Cap Seal
Incorrect Grade Motor Oil
Bad TPS - influences fuel ratio (trim)
Bad Knock Sensor (retards timing)
Bad Coolant Temp Sensor - (also regulates fuel/air ratio based on (perceived) temperature)
Failing Thermostat - so engine runs too cool.
Faulty Grounds - if corroded cause weak spark
Ignition Timing off - have it checked.
Failing Fuel Pump
Dragging Brake
Dragging/malfunctioning parking brake
Clogged/bad PCV Valve
Blocked or empty Catalytic converter
Primary O2 sensor
Leaking or Dirty Fuel Injectors

These are all potential causes of poor fuel economy.
