How to deal with abnormal sound of vehicle throttle position

This may be caused by internal stagnation or excessive carbon deposition in the throttle. Clean up the carbon deposit in time and replace it if necessary. In addition, it may be the abnormal sound of the idle valve. It is recommended to go to the 4S shop for detailed examination and targeted treatment.

Throttle is a controllable valve, which controls air to enter the engine. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned to do work. It connects the air filter and the engine block, and is called the throat of the automobile engine.

How to clean and prevent should pay attention to:

1, which should be dismantled and cleaned;

2. Correct some misunderstandings of throttle cleaning;

3. The main cause of throttle scaling is oil vapor, followed by particles and moisture in the air, that is to say, when the qualified air filter is removed from the crankcase ventilation pipe, the throttle scaling speed will be much slower.

When cleaning the throttle valve, it is not necessary to disassemble it, but it is necessary to clean the sealing part of the inlet steam. Idling motor must be removed before cleaning. Cleaning the nozzle and avoiding disassembly have their own advantages and disadvantages. Generally speaking, the maintenance station suggests avoiding disassembly and cleaning to prevent other unnecessary waste, such as replacing sealing rings or other gaskets after disassembly, or oil and gas leakage during disassembly and assembly, which will delay the owner's time.
