V70 2.4 petrol fuel problem

Hi . I have problem for long time with my V70 (non turbo). She does not accelerate properly(only sometimes ,untill I stop). I bought Vida and tray to find where is the problem. All parameters looks ok,no errors etc. Only issue I think is fuel.
When I cranking engine fuel pump duty cycle show me around 30 percent. After that drops to 7-10 percent even on hard acceleration. I have checked pressure at idle and seems to be ok -3.8 bar (Vida show me 567kPa, minus 40 temp).Also when I pressed gas pedal at idle knock sensor retard 5% ignition and 4 cylinders count 1 or 2 misfire at this time and disappears quickly.
I have attached few screen shoot from Vida. Any help from you guys? Thanks
