i recently bought Honda city 2002 exis , the car is on CNG and petrol . it does 100 km in on full CNG cylinder with AC on . but on petrol the average is very poor i get 150 km on half of fuel tank again AC on . please advise what could be the problem . i have change the plugs and throttle is cleaned also . please advise what could be the reason for poor petrol average .
Clogged Fuel filter, Leaking of injector, timing too much advanced (Due to cng installed ). Check for these first. I had a same issue couple of months earlier, culprit was abnormal spray pattern of injectors so i replaced them.
P.s. The mileage is very poor i get around 12 in AC (Light foot & shifting below 2500) & without AC 13.5 to 14 on petrol. Engine is D15
Thanks mate for the reply . i drive very carefully as well just like you change gear around 2500 or 3000 mAX . i haven't found a good mechanic who can fix these issues . i live in DHA Phase 1 . could you please recommend a good mechanic in karachi . or the one you use perhaps . by the way i went for 15 inch honda alloy rim as you recommended .
