Mechanical failure, such as ignition coil, spark plug and fuel injector. Resulting in a shortage of cylinders. 4. Low oil pressure or cylinder pressure leads to insufficient power. 5. The fuel quality is unqualified. 6. Idle speed control valve is damaged or dirty. 7. Air leakage in the intake manifold. 8. Engine arm or claw pad is damaged, etc. 9. Oil oxidation or low grade is mainly due to poor fluidity at low temperature, and engine cold start protection is not in place. When the car is shaking, it is recommended to go to a 4S shop or a repair shop for inspection and repair to improve the safety performance of the car. Million car purchase subsidy
