Perform a complete tune up and service of the vehicle, inspect tire pressure and brake components, and ensure none of your filters (air, fuel, transmission) are in need of replacement and go from there.

Thanks.
I did all of the above and did not notice any difference in my MPG. A friend suggested cleaning the Idle Air Control Valve. How do I clean it and are any manual adjustments needed after it is cleaned and reinstalled?
thanks,
