What Causes Engine Shaking When Driving a Car?

[GiannaRose]

Car engine shaking while driving can be caused by: 1. Fuel system issues: Clogged fuel lines leading to poor fuel supply, manifested as engine shaking, unstable idle, or stalling while driving. Fuel pump failure can also cause engine shaking; 2. Electrical system problems: Check if the timing is accurate, as abnormal ignition is usually a timing issue; 3. Spark plug inspection: Check if the spark plugs are worn out, if the gaps are uniform and unchanged. A malfunctioning distributor can also cause engine shaking. An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, electric motors, etc.
