Cutoff at low RPM during gentle acceleration - Yaris Verso 1.3 VVTi - Toyota Yaris Forums

I get short engine cutoff which causes jerky acceleration.
It happens at low RPM, around 1200, on each gear.
The best way to present the issue is to try to drive over a curb from complete stop. I have a steep entry to my garage, you can see in the video, where I keep the throttle gently and steadily pressed in: https://www.youtube.com/watch?v=Ll7Rh31lpc8

Other than that the car runs super smooth but there's a problem with fuel economy. Car's display shows 6.5l/100km average but real consumption is 8.5l/100km (calculated from distance driven and fuel tanked).

I exchanged Mass Air Flow sensor with my Prius but even with MAF sensor completely disconnected the issue stayed there. I ordered a new front O2 sensor but I get a feeling it will not sort it out.

Would anyone be able to help me before I go to Toyota dealership and before I spend too much money there?
