Re: Gas Mileage
Tune-up? When was the last time you did a complete tune-up? Plugs, wires, cap, rotor, air filter, pcv valve. A bottle of injector cleaner wouldn't hurt either. Does it run okay? Do you smell gas? Where does your temperature gauge stay? (stuck thermostats are a common problem with these things and if the temp. doesn't get high enough the computer won't go in closed loop and this will hurt your fuel economy...mine used to stay a little below a 1/4 and I didn't know it was a problem til I came here, I changed the thermostat and got another 1.5 mpg)
Unrelated:
If you haven't done so you are also due for an antifreeze change too. You need to change your radiator cap with one not made by AC Delco too.
