What Causes the Engine Warning Light to Illuminate and the Vehicle to Shake?

[MacElliot]

The reasons for the engine warning light illuminating and the vehicle shaking are: 1. Poor combustion of the engine's air-fuel mixture; 2. Abnormal fuel supply pressure; 3. Wear of the spark plug electrode gap; 4. Faulty ignition coil; 5. Aging rubber components of the engine mount or transmission mount; 6. Clogged throttle body. The solutions for the engine warning light illuminating and the vehicle shaking are: 1. Replace the ignition coil and fuel injector; 2. Replace the spark plug components; 3. Replace the rubber components of the engine mount or transmission mount; 4. Clean the throttle body. The working principle of the engine is to generate kinetic energy by burning fuel in the cylinders, driving the pistons inside the engine cylinders to reciprocate, which in turn moves the connecting rods and cranks attached to the pistons in a circular motion around the crankshaft center, thereby outputting power.
