What Causes Engine Shaking While Driving?

[LeMaya]

Vehicle engine shaking while driving can be caused by: 1. Damaged spark plugs where the electrode gap wear leads to insufficient spark ignition, resulting in incomplete combustion of the air-fuel mixture; 2. Poor fuel quality causing inadequate atomization by the fuel injectors, leading to incomplete combustion in the cylinders; 3. Excessively dirty throttle body or excessive carbon buildup in fuel injectors; 4. Abnormal fuel pump pressure or faulty readings/malfunctioning of the intake pressure sensor. The engine's function is to convert thermal energy into mechanical energy by burning fuel in sealed cylinders to expand gases that push pistons, thereby providing power to the vehicle.
