High fuel consumption

Post by duri_svk » Fri Jul 22, 2011 1:36 pm

Hi to all,
I have high fuel consumption on my B18FT engine after Engine overhaul. I cant go under 10L/100km on highway (in city app. 12L/100km). Everything is new on the engine besides MAF. What should I check ? Please advice me to solve this problem.

Does it use an oxygen sensor? If so change it. They have a limited lifespan.

I just did this on my 850 and turned 13l/100kms to 9l/100kms. Needless to say, I am now very happy.
