Try using BG 3 step fuel injection service and run an extra can of BG injection thru air intake. Clean the carbon out of the thottle body with intake cleaner. Usually you can go the most dealers to have the BG service done most dealers use it. Some aftermarket shops use BG products. Try running a higher octane. The service usually runs between $100-$150. And 9 times out of 10 it will give better mpg.
