HIGH FUEL CONSUMPTION

[Shiyam A]

Hi dear My Vehicle is Daihatsu HIjet Year 2007 model Buddy van. I have done full engine tuning in a proper way. But still, it works 8 km/per liter. When I stop the vehicle petrol smell is coming. Please advise me. My vehicle's model number is SV320.

If you get petrol smell, check for leaks

Check for leaks. Also check the charcoal canister.

Also...when you say a tune up was done the proper way...what exactly does that mean?

Did this (petrol smell) start happening after the tune up ? or was it there before the tune up ? If the tune up was done after the petrol smell started coming did the people who did the tune up find anything strange/wrong ?
