Car acceleration abnormal noise is caused by engine carbon deposits, fuel system failures, etc. The specific reasons and solutions are as follows: Engine Carbon Deposits: Long-term incomplete combustion causes carbon components in gasoline to remain inside the engine, forming carbon deposits. Excessive carbon deposits can lead to engine shaking, abnormal noises, and other issues. The solution is to use fuel additives to clean the carbon deposits. Fuel System Failure: During acceleration, the engine needs to output more power, which means the fuel system must supply more fuel in a short period. If any part of the fuel line or fuel injector is clogged, fuel cannot participate in combustion in time, leading to weak acceleration and abnormal noises. The solution is to perform repairs.
