I was wondering if anyone has the same situation I have, I go to college here locally but travel on the weekends down to marietta, about ~135 miles one way to see my g/f. I know this car already gets good milage but I was wondering if there is anything I tune to set-up, whatever, to get the car get even a few more miles to the gallon? I was thinking of doing the wires, dist. cap/rotor, spark plugs, clean or buy new injectors, I also use syn. oil. I get about 22 with mostly city and some highway driving, which isn't bad. I can guess about 26 on the highway, maybe a little more. I know people say when you O2 sensor goes out you get like 14 mpg so mine is good but replacing it help any? Anything else out there to do to help? I have a set of Guru chips in it, does that affect anything? THanks
