i did some searching in this board for threads on gas mileage w/o much help. i have a lot of miles on my car and only 23mpg highway, and i am a one person commuter at that! things i have done and it didn't fix: o2 sensor change, egr check, air and fuel filter change, spark plugs-wires-rotor-cap, oil change, reset ECU, timing set at 20degrees, idle at 750 (i have an automatic), added bottled fuel injector cleaners, and i always fill up with 87 octane at chevron, by the way i have original muffler and the tip of exhaust is pretty clean so i know i am not burning an unusually rich mix right now. for those that don't know, i am running basically stock now. anyone got 2 cents on this???
