Whens the last time you cleaned your Mass Air Flow sensor??
Its amasing how impotant this service can be.
Not hard to do yourself, but it is delicate so bee's careful.

Also, every 25000 or so miles I use a product Called BG44K its a engine top cleaner that does an incredible job on the valves , ingnition chambers and piston tops. Helps improve mileage also. You can get it at most GOOD auto parts stores. Its pricy, but works! And it WONT harm your O2 sensor!!!
Speaking of wich, if yas havent changer that forever (O2 sensor) thats another thing that should be changed every 50000 or so!
Also, another thing to check is the brakes!! YES the BRAKES. Its amasing how many are driving around with collapsed rotors causing drag at their wheels. Especially if tis four wheel disk brakes.
I have a high air flow filter. (K$N). My truck is however always in good tune. When I installed it I didnt really see that much gain in Fuel economy,(Maybe a mile or 2 per gallon) but performance was a BIT better. I think a standard air filter that is kept in good condition (clean ) works just as well. Unless yas wants to spend the money and have a cool window sticker! :wink:
A Cat back exhaust MAY help!
lastly KEEPS YER FOOT AWAY FROM THE FLOOR BOARD!!!! :lol:
