Why is the car throttle always dirty? How to clean it?

Because engine oil and gasoline may stick to the valve at high temperature and form carbon deposit on the throttle, it will affect the opening and closing of the valve in serious cases and feel that the engine is weak.

There are two methods to clean the throttle valve, one is disassembly-free cleaning, and the other is disassembly-free cleaning.

Disassembly-free cleaning is relatively simple, and there is no need to replace some sealing rings, gaskets and other parts.

Now, in most cases, disassembly-free cleaning is adopted, but if the oil pollution jam is particularly serious, it needs to be disassembled for cleaning, and even the cylinder head should be uncovered for cleaning in serious cases.
