Hi,

This might be normal for electronic throttle, but this hand gets jittery often. I don't really feel much going on while it does this.

Hi,

I watched the video. In all honesty, I don't see anything out of the ordinary. The movement could actually be a slight increase or decrease in RPM's that is so minimal you don't hear it. I wouldn't be overly concerned.
