I just recently installed a Scangauge on my car, and I have been trying to figure out what my car likes as far as gas mileage is concerned. In doing this, I have noticed that my car goes into open loop at anything above about half-throttle. I understand that Honda's (as well as most other cars) go into open-loop under WOT, but my car is doing it long before WOT. I am wondering if this could be a sign of the O2 sensors being bad? Any ideas? Thanks for your help.
