This car has 127k miles. Battery never been replaced. I was thinking about replacing it since I expected high 50s fuel economy... however the more I learn about this car it seems that it's economy mostly depends on where you drive. The docs I've seen on CleanMPG seem to suggest 40mpg during acceleration, and in that context the mpgs I've seen make sense because there are stops every half mile here it seems and lots of rolling hills so the car is in a constant state of acceleration and deceleration. I suspect 45 mpg is likely the best I can manage, although I do wonder about the acceleration problems... the accel is about half what it is for my Corolla 2002. What could that be about?

Regarding ODBII, I tried to read codes with an Android reader that works on the Corolla, but the vehicle wouldn't power it. Do Honda and Toyota use different ODBII standards?
