I still don't think it's back to normal, though. Does it take time to adapt to the new O2 sensor? I'll admit I'm not entirely sure how the ECU does its figuring regarding all this...
Well, resetting it constantly won't exactly give you accurate impressions of you MPG unless you are letting a decent number of miles pass each time. My city driving will cause the "average" MPG reading to fluctuate between 12mpg and 20mpg. It usually averages out to 18.6 b/c I have a shitty commute.
I guess it could take time to respond to the O2 sensor. If you really want to do a hard reset, unplug the negative battery terminal for 15+ minutes and see if that helps.
