What Causes the Car to Shake After Coming to a Stop?
2 Answers
The shaking of the car after coming to a stop is due to excessive carbon buildup in the engine, which requires cleaning. Carbon deposits can accumulate in various parts, including the throttle body, fuel injectors, intake manifold, and spark plugs. It is important to address this issue promptly, as it can affect the vehicle's power performance and fuel consumption. Cleaning Method: A bottle-shaped tool is suspended above the engine, and a cleaning agent is poured into it. The cleaning agent is then introduced into the engine through a tube to remove the carbon deposits. This method of carbon cleaning is quite common. Engine Function: The engine in a motor vehicle is a machine that converts other forms of energy into mechanical energy. The engine can refer to either the power-generating device or the entire machine of the power unit.
I also experienced parking vibration issues with my old Passat before, and later found out it was caused by worn engine mounts. The rubber damping blocks between the engine and frame harden and crack over time, causing engine vibrations to transmit directly to the cabin. Additionally, excessive carbon buildup in the throttle body can cause this, especially in vehicles with frequent auto start-stop. If fuel injectors are clogged causing unstable fuel supply, RPM fluctuations will lead to noticeable shaking. Worn spark plugs causing uneven ignition or aggressive AC compressor engagement can also create significant vibrations. These are all common causes - I'd recommend starting with the simplest check: throttle body cleaning.
