Well I have KIA Sophia 2001, DOHC, 16V engine, 1500cc.
fuel consumption is quite a big issue for me, it gives the average of almost 6 to 7 km/ltr.....Any help? :(

Did you solve this issue?

My first step would be to clean the air intake with a can of Seafoam spray (see the sticky post with Seafoam) or air intake cleaner from parts store, the next is to get the exhaust tested (pre-cat bad?). You might want to create a baseline by tuning-it up and replacing all the filters and go from there. I would also question it's performance..., vacuum hose leak
