Then 4 days ago the car stared shaking only when I stop, but soon I take of it does stop shaking.

It sounds like your vehicle may have a broken vacuum line to the intake manifold. Check the Positive Crankcase Ventilation (PCV) vacuum system and vacuum lines for leaks by listening for the vacuum leak. This is why the engine runs rough at idle and smooths out when running higher. If you’d like, a certified YourMechanic technician can be dispatched to your location to inspect the engine vibration and help you diagnose and confirm what repairs need to be made.
