KSP90 VITZ/YARIS 2007 poor fuel economy

[wasay_ahmed]

Well KSP90 1krfe powered vitz is giving poor mileage. Hardly covers 200kms in a full tank though 8kms/litre max and with Air-condition 6.5kms/litre

So far below jobd have been performed but results are still same.Infact the car felt to be running easy after new plugs but only for a day.Feels like running rich yet the response of car is very good.

Intake manifold service.

Valve Clearance checking ahh the stupid mechanic didnt told the reading to my driver
Toyota CVT FC gearoil with Pan cleaning
Brandnew tyres wheel balancing and alignment on stock 14s the tyres are not much oversized indeed.
