Honda City 2008 automatic mileage problems

[h.musvi]

I have city 2008 auto, i commute between wah cantt to islamabad daily .. it was having an average of 13km per litre. Recently after getting the tuning done .. mileage has decreased . I ve changed plugs, done the throttle cleaning and changed gear oil as well and after doing all this .. the mileage has gone down.

Please suggest some solution.

check tyre air pressure and air filter. you may need to change air filter if chocked.

Pz check its injectors and coils, if they are fine then it must be Air Fuel Ratio sensor, i travel on the same route as yours
