I was driving home on Interstate, from Baltimore to Cincinnati, and noticed I was getting way better MPGs than I normally do. 34 mpgs to the gallon. I normally get 25 to 26 on the highway. I hooked up my scanner and my LTFTs were at a -22. They are normally 0 to -2. Does anybody have any idea what is going on? My wideband was in the 14s so I'm not sure what is up. Maybe a bad o2 sensor?

How long did it stay that way? Obviously when you are cruising your ltft's are going to go negative since you require alot less fuel at cruise.

The whole trip. They stayed close to that for almost the entire time. Never getting near 0. I have unplugged my battery for a few hours today to try and reset the computer but they are still way negative. -14 or so.

I haven't messed with the car at all lately. I will try cleaning the MAF and see what happens.
