Symptom Chart: Engine-Speed Related Vibrations

WARNING: This page is about a different car, the 2018 Ford EcoSport. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: When an engine-speed related vibration is present, engine, engine accessory and engine firing calculations should be carried out.
NOTE: Any assembly that is out of balance will only cause a first order vibration, it will not cause a higher order vibration.
NOTE: Some powertrain-speed related vibrations are normal though they should not be felt in the passenger compartment.
