Hi,

Ok, the best thing to help increase gas mileage is to do a direct induction cleaning of the intake manifold and fuel injectors.

You will need a can of SeaFoam cleaner, a funnel and a helper.

Disconnect the large vacuum hose at the brake booster(this goes directly to intake manifold). Have helper crank engine and every few seconds, goose the gas pedal to keep engine from stalling. Stick funnel in end of disconnect vacuum hose and slowly pour contents of Seafoam into funnel.( It will smoke white out the exhaust when doing this, which is normal for this procedure.)

Once done, reconnect vacuum hose and drive for about 5 miles at hwy speeds to finish cleaning out carbon.

the above will clean carbon from valves, intake manifold and injectors.

Cost you about $10 total and will be almost identical in results to the direct induction cleaning from a shop that charges $120-150

I would also suggest using some throttle body cleaner and a rag to clean out the throttle body.
