Readers, Mr. Lin asked: when the car is accelerating, the throttle has abnormal sound, and the engine is shaking very clearly. What do you want to do? Reply: This is the reason for the existence of carbon deposition in the intake system. It is recommended that the repair shop be cleaned. The engine shakes also has to go to the maintenance shop for inspection. The main object is the data analysis of the engine control unit and the combustion chamber. If the engine detonation sensor signal is mismatched, the above acceleration abnormal noise will be caused.

What is the reason for this? Answer: the general automatic transmission is compared with the front brake pad, because the same system is used for braking and clutch shifting. The front wheel brake dust depends on the material of the brake pad. It should not be a problem. Reader, Mr. Tang asked: Recently, the remote control lock of the automobile was found to be out of order, and there was an artificial signal disturbance nearby. What is the reason for this?
