I have Honda Civic 2015 Prosmatec (Rebirth)
My vehicle is currently experiencing suboptimal fuel efficiency in the city. Previously, it achieved approximately 8 KM/L, but it has now dropped to around 6 to 6.5 KM/L.
Here is a summary of the steps I have taken thus far to address the issue:
-Replaced the fuel pump and filter with genuine Denso parts, ensuring the fuel pump pressure was checked before installation.
Changed the Honda ATF fluid and replaced the transmission filter with a genuine part.
-Swapped out the old ignition coils for new genuine replacements.
-Serviced the radiator and installed a new thermostat valve; I also replaced some rusted water flanges and serviced the ATF cooler, filling it with Honda green coolant.
-Had the radiator motors checked; they are functioning properly.
-Cleaned the throttle body, air intake, and several sensors using NASA cleaner.
-Performed throttle body calibration.
-Installed genuine air and oil filters, along with Honda 5W30 engine oil.
-Ensured the tyres are in good condition, maintaining a pressure of 30 PSI.
-Serviced the EGR (Exhaust Gas Recirculation) system.
-Changed the spark plugs.
-Cleaned the catalytic converter with a specialized cleaner.
-Had the brake calipers serviced at the Honda dealership in Karachi.
-Installed a new battery.
-Completed ultrasonic cleaning of the fuel injectors.
There are no error messages displayed, nor have any issues been detected by the scanner.
@Xulfiqar Bhai your guidance is needed.
Thanks
