How to Solve Car Shaking Issues?

[AlinaRose]

Car shaking causes and solutions are as follows: 1. Severe engine carbon buildup: The most common cause of car shaking is a dirty throttle body or excessive carbon deposits in the fuel injectors. When there's too much carbon buildup inside the engine, the gasoline sprayed by the cold-start injector gets largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making ignition difficult. The solution is to clean the fuel system and check if the idle control valve has carbon buildup that needs cleaning. 2. Ignition system problems: Check the working condition of spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or improper spark plug firing can also cause such symptoms. The solution is to check if spark plugs have excessive carbon buildup and replace them if necessary.
