Hello,
Since I've change the intake from my 1.6 3zz-fe engine on my corolla there is arithmias only on the cold start. The modification that I did was intake manifold, injectors, and maf all the parts was taken from 1.8 e1z-t72 engine which was an avensis car. Is there any idea what this problem could be? Keep in mind that I swap the old MAF as i was 100% sure that was in a working condition.
