Post gas mileage

i have a 92 4runner that runs pretty cherry. about 260000 miles on her. i just re balanced my rear drive shaft and replaced u joints. but i have been noticing that lately my gas mileage has been going down. im going to get a new filter (K&N) and i was also planning on cleaning/replacing my PCV valve because i heard that helps. what else do you guys suggest i do to improve my gas mileage?

Step lightly on the pedal.

The K&N ain't gonna help 'ya, especially out here in AZ.
They let a lot more stuff through than an OEM style.

And mileage going down is pretty much in line with the ethanol content in pump gas going up.

Out here in hot,sunny, dusty Arizona the ethanol content only goes up in the winter then drops back down in the spring.

lo323 isn't exactly helping us by giving any numbers, so it's kinda tough to see what he's seeing

Welcome to the 4Runner club. Mine gets 8-10mpg rolling around town, and it is all stock except for an electric fan replacing the factory belt driven fan.

clean the KnN, mine is just fine...

big thing to do tho, is to make sure that the cap/rotor/plugs/wires are all in good working condition... i replace mine about every 30-40K miles...

like abe said, step lightly, and clean out your stock intake tube and throttle body... im sure theres build up there...
