hmm.... 20MPG highway......something must not be right I drive 100 mile round trip (mostly interstate) to work each day, and am filling up 15 gallons at about 300 miles... sucks. FWI dropped it down from 22, but from what I'm see here, that still sucks compared to the rest of you. Only 64,000 mile on it too.

I read a couple threads on replacing the front o2 sensor, and that should help, I just wish there was a way to check it before throwing parts at it.....

Thanks in advance for the help!
