I have the ES model. Its indication says that the fuel average is 20.8km/l but actually it is giving around 12.5km/l.
I have changed the throttle because the last throttle was giving 1500 rpm and now the new one is giving 900 rpm.

Now, the ignitor plugs and everything is in a good condition as per my mechanic (after checking out electronically).

So what should I do now in this condition?

Fuel mileage is very subjective and varies very much according to driving conditions. If vehicle is used mostly in heavy traffic areas, the mileage would definitely not come up to the average.

Have you done an actual run to confirm the average mileage?
