Engine malfunction refers to engine failure.

1. Generally, it is a fault caused by the throttle being too dirty.

2. When the carbon deposit is excessive, the friction between the throttle and the inner cavity wall increases, resulting in the throttle not being able to close normally after being opened. During the vehicle's self-inspection, the fault light will light up.

The throttle, which is connected to the air filter on top and the engine cylinder block below, is a controllable valve for the gas to enter the engine. Figuratively speaking, it is the throat of the car engine. It is related to the acceleration of the vehicle. Keeping the throttle clean all the time can keep the acceleration of the car smooth and also reduce fuel consumption.

Specific cleaning method:

1. Disassemble the engine cover, which is to facilitate the disassembly of the pressure pipe and other pipelines under the cover. Precautions: Do not let the screw fall into the engine; when disassembling the pipelines outside the pressure pipe, you can preheat the car.

2. Remove the throttle: Unscrew the screws and collars that fix the throttle, and remove the throttle and place it on a rag. Precautions: Be careful to block the air passage and prevent foreign objects from entering the engine cylinder block.

3. Clean the throttle: Most of what adheres to the throttle is a mixture of engine oil and gasoline. Spray the cleaner on the dirty area, wait a moment, and then wipe it. Precautions: The gap is prone to dirt and should be wiped clean.
