What Causes Idle Shaking, Lack of Power During Acceleration, and Jerking?

[DelDamian]

Here are the possible reasons for idle shaking, lack of power during acceleration, and jerking: 1. Spark plug electrode erosion Severe erosion of spark plug electrodes, high-voltage wire leakage, or carbon buildup in the throttle body may be the cause. If the oxygen sensor malfunctions, it will affect the electronic fuel injection system, leading to idle shaking, lack of power during acceleration, and jerking. 2. Regular inspection: If the car exhibits shaking at idle or lack of power during acceleration, it indicates a fault in the engine system. The first step should be to inspect the condition of critical engine components, especially those affecting the ignition system, such as spark plugs. During daily driving, it is essential to regularly check the condition of car components and replace faulty parts promptly to maintain optimal performance.
