I havn't check anything for leaks so far so there could possible be a vacuum leak, but my mileage has always been crappy since I started driving my car.
Just this past summer I bought a crappy Ractive air filter as a temporary solution for my cold air intake. Once spring comes, i plan on redoing all my intake piping and buying a K&N filter. I bought a 65mm tb and once it comes I'm going to buy a ported UIM and throw that on as well.
One thing I haven't done in a while is fuel injector cleaner. I've never had any luck with them anyways so I actually don't care for them.
I intend on buying the O2 sensor tomorrow and filling up and seeing what my MPG is like. I'll probably post my results if there was any improvement.
I also heard that the "winter blend gas" also has some sort of effect on mileage too so that could also be a contributing factor.
