thanks for the video. in my case the knocking doesn't happen the first moment I kick down, it happens around 1800-1900 rpm. it doesn't make any noise, it feels like an engine hiccup, the passengers can feel it too when they pay attention. I also get a few random knock/bump when I am siting warming up the car in the morning. Does anyone get that?
