How to clean the throttle of a car?

2. Remove the black trim panel on the upper part of the engine.

3. According to the structure of the vehicle, the air inlet hose can be loosened or removed. Generally, there is a black rubber tube between the air filter and the gas meter, the shell is plastic and the throttle is metal. Dismantling this kind of air hose is generally a relatively large metal clip, some of which are threaded clips and some are spring clips, so you should choose a cross screwdriver or needle-nosed pliers to disassemble it according to the different clips.

4. Remove the throttle. Try not to unplug the throttle harness at this time, because some models will reset some programs and data inside the throttle after plugging and unplugging the harness, which will bring unnecessary trouble. After the throttle valve is removed, the air inlet at the metal end should be blocked with a rag to prevent foreign objects from entering the engine block.

At this time, we can clean the throttle with cleaning agent or detergent. When cleaning, pay attention to the carbon deposit inside the throttle valve, the root of the throttle shaft and the throttle valve with bypass valve. Even if there is a small hole next to the throttle valve, the bypass valve channel should be cleaned.

6. After the throttle is cleaned, dry it with a rag, and add a small amount of engine oil near the throttle shaft for lubrication.

7. Now, you can install it in the reverse order of disassembly steps.
