update on car problems
and replacing the O2 sensor, still i get gas mileage around 270-280 and have hesitation.
anymore suggestions/ideas? plugs, cap, rotor, distributer are all fine. the mechanic ran a diagnostic test on a computer and it said that the air/fuel mixture was out of whack. he replaced the O2 sensor and after testing it on the machine, it said that everything was back to normal. and of course it isn't
help please :*(
