What is the solution for BMW X1 shaking?

[VonKathryn]

You can replace the spark plugs or clean the throttle body to solve the shaking problem. Here are the relevant introductions: 1. Spark plugs: Spark plugs are important components of the gasoline engine ignition system. They introduce high voltage into the combustion chamber and cause it to jump across the electrode gap to generate sparks, thereby igniting the combustible mixture in the cylinder. They mainly consist of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell. 2. Throttle body: The throttle body is a controllable valve that regulates air intake into the engine. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture, which then burns to perform work. It connects to the air filter at the top and the engine block at the bottom, and is known as the throat of the car engine.
