whens the last time u changed / cleaned the air filter, checked the plugs, changed lubes (engine, tranny, ect)

 

just instlled a new k&n cold air around 1000 miles ago, oil change is in 200ish miles, and i had the tranny down not to long ago repolaceing the back freeze plug and put all fresh in it then. its a standard so i should be getting a lil better milage anyway right??? and recently installed flowsmaster 80series. changed plugs 4000 miles ago and wires 500 miles ago.

 

City/Highway has a lot to do with your mpg.

That and your driving habits.

 

The manual specs at 1mpg better than the auto and then on highway only. It really doesn't help that much unless you use really conservative shift points.
