[pwuser152968829682]

Salam.

My honda civic 1.8 oriel 2020 model was giving me perfect fuel average of 8 to 9 km/l daily. After the rain suddenly average dropped to 2.8 km/l even I didn’t drove the car in deep water. I contacted honda’s dealership regarding the issue and they called me up for general tune up including throttle service and air filter replacement.After all things getting completed Currently I am getting 4.8 km/l even with the light foot means no rpm above 1500 to 1700. I am new here please share help regarding this issue.

14000 kms total driven, 1st owner

waelekum salam, bro you have to check harness connector of coolant, O2, and maf sensor its may change to corrosion due to rainy humidity, although connectors installed with seals but it may change. i had such case fixed the problem.
