Why Does the Car Shake When Shifting from D to N Gear?

[JesseLynn]

The reasons for the car shaking when shifting from D to N gear are as follows: 1. Severe engine carbon deposits: The most common cause of car shaking is a dirty throttle body or excessive carbon buildup in the fuel injectors. When there is too much carbon deposit inside the engine, the gasoline sprayed by the cold start injector will be largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making it difficult to start. 2. Ignition system issues: Check the condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or improper spark plug firing can also lead to such issues. 3. Unstable oil pressure: If you have already cleaned the engine carbon deposits, cleaned the throttle body, replaced the oil gasket and spark plugs, but still notice the car shaking, it is recommended to visit a 4S shop to check the fuel supply pressure and the intake pressure sensor. Abnormal fuel pump pressure or incorrect readings and poor performance of the intake pressure sensor can also cause the car to shake.
