What are the symptoms of excessive carbon deposits in the combustion chamber?

[MacJasper]

Excessive carbon deposits in the combustion chamber can cause symptoms such as weak acceleration, engine knocking, shaking and weakness, and increased fuel consumption. Here are the detailed explanations: 1. Weak vehicle acceleration: Carbon deposits accumulating on the throttle body can lead to weak acceleration and idle shaking. 2. Engine knocking: Carbon deposits in the combustion chamber reduce the chamber's volume, increase the compression ratio, and cause uneven power output among cylinders, resulting in engine knocking. 3. Engine shaking: If carbon deposits accumulate on the fuel injectors, it can affect fuel atomization, leading to uneven fuel injection and causing engine shaking and weakness. 4. Increased fuel consumption: Carbon deposits on the throttle body can alter its position and result in incomplete fuel combustion, thereby increasing fuel consumption.
