The TB is driven by a stepper motor so it should be smooth. I never watched it but I would not expect it to jump like that.

It could be the signal from the pedal senor or the TB stepper motor. You should hope for the TB because the pedal sensor assembly is stupid expensive.

Buy a new TB on Amazon for <$100.
