2007 Toyota Corolla GLi 1.3L with fuel efficiency issues

[pwuser175134427049]

Hi everyone,

I need some help. I have a Toyota Corolla GLi 1.3 (1300cc) 2007 model. Its fuel average has dropped to only 9 km/l.

1. I took it to the mechanic:
2. All sensors were checked and scanned
3. Fuel injectors were replaced

But still, the problem is not solved. The car runs smoothly otherwise. There is no unusual smoke or missing.

Can anyone please guide me on what else I should get checked to improve the fuel average?

Thanks a lot!

How do you check your consumption? At what routes is it used

Fuel injectors were replaced

Why get rid of your original fuel injectors? Did you replace them all with used ones?

All sensors were checked and scanned

Did you take the technician for a drive so he could look at the data live?
