I hope you all are good. From last 6 months My Honda CITY is giving me very bad mileage of even 7-8 in city with A/C and almost 10 without A/C. I recently replaced its all plugs with NGK plugs and genuine air filter, but there isn't any change in milage. It was giving me milage of almost 16 on long without A/C a month ago but now its giving me 13-14. Can anyone guide me whats the issue. May be its the O2sensor or the fuel injectors? Car isn't showng any electrical issue as i have gone through the scanning process.
