Acceleration hunt on n52b25a
Hello! I am facing a weird issue with my n52b25a europe version of 218hp and 2.5l. Whenever I am in N or Parking, when I try to maintain a steady acceleration between 1000-1500rpm, the acceleration won't stand still and it drops. From 1500 to 1000 or 1100 and from 1000 to 900. Past 1500 rpm everything is fine. Cars runs a bit rich since lambda voltage before cats are 2v on both banks and I know the value should be 1.5V optimal.
Changed maf, vanos solenoids, lambda sensor. Any ideas would be appreciated Video below https://www.veed.io/view/a4f04c7d-7f...ue&panel=share |
