Can someone help with diagnose injector correction Diagbox?

[amigo]

Hi

I got some cuts out when the car is in idle and i think i have a problem with 1 or more injectors? I have made a video when the car is in idle and at 1500rpm. and when all numbers is the same on the video its rev 2000rpm.

I cant understand the flowing hogn and low numbers but i do think there is some problem with 1 or more injector or the HP fuel pump.

some advice?
