ive seen bad o2s cause driveablility issues on these engines without an engine light but it only knocked mileage down 3-5 mpg. even if you unplug the sensor and run in limp mode they still get high 30s low 40s.

what about fuel injector spray pattern or leak down after sitting?could someone have replaced the injectors with larger ones? the cx and vx came with 190cc injectors i believe. dx,ex,lx,si came with 220cc. maybe a previous owner had them replaced and didnt know they were different?
