    Can you explain further please - from your video the RPM seems to be ok to me. Do you mean it goes too low or do you mean it stays too high after pressing the accelerator?

    I think that engine works wrong because on idle I feel vibrations in car and engine pulls slightly.

    In the video, did you press the accelerator yourself or did the RPM go up by itself?

    In the video on 0:32 accelerator was softly press. Problem is when accelerator isn't press. When engine work on low RPM, feel in car engine vibrations.
