What Causes Car Engine Vibration?
2 Answers
The causes of car engine vibration are: 1. The engine throttle is dirty or the fuel injector has excessive carbon deposits. During cold starts, the gasoline sprayed by the injector is largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture and difficulty starting; 2. Poor performance of the ignition system, including spark plugs, high-voltage wires, and ignition coils; 3. Abnormal fuel supply pressure, incorrect intake pressure values, and malfunctioning sensors. Solutions for car engine vibration: 1. Clean the fuel system and inspect the idle speed motor to remove carbon deposits; 2. Check if the spark plugs have excessive carbon deposits and replace them if necessary; 3. Inspect the fuel pressure and replace faulty components.
As someone who drives frequently, I've found that car engine shaking can have several causes. The most common is an issue with the ignition system, such as old and eroded spark plugs or faulty high-voltage ignition coils, leading to irregular ignition in certain cylinders. Another possibility is insufficient fuel system performance, like clogged fuel injectors or a dirty fuel filter, affecting the air-fuel mixture supply. Additionally, a dirty air filter or carbon buildup in the throttle body can also cause shaking, especially during startup or acceleration. I've also experienced vibrations from worn transmission clutches or slight resonance due to aging suspension components. Once the engine starts shaking, it can easily lead to loss of control while driving, which is very dangerous. Therefore, I recommend immediately pulling over to check the spark plugs and air system, and if that doesn't help, go to a professional shop for a comprehensive inspection without delay.
