Clean the throttle again? Where does the stain on the throttle come from?
When servicing a vehicle, there is usually a service called throttle cleaning. But what the hell is the throttle? Why clean it? Why is it dirty?
This is the throttle valve. The throttle valve controls the air intake of the engine. The current throttle valves are all electronic, and the cable is cancelled. Therefore, the stable idle speed is also controlled by the throttle valve. If it becomes dirty, the idle speed will be unstable and serious. Cold start is difficult, and the fault light will be on. Generally speaking, cleaning the throttle valve is simple, but there are also unreasonable designs that are more difficult to wash!

The car hasn't been driven for half a month, nothing has happened! At most, there is a thick layer of dust on the car, just wash the car. Everyone may wonder whether the battery of the vehicle will run out, whether the engine oil and the entire vehicle oil will deteriorate or solidify. First of all, the battery will not run out in a short time, and the entire vehicle oil will not solidify.

Many people on the Internet say that the oil will deteriorate when the car is left for a long time. This is too far-fetched. Generally, the shelf life of motor oil is about one year. Although it may be changed after adding it to the car and mixed with oil sludge, etc. Resistant for half a month. It ’s just that after a long period of time, most of the engine oil in the engine has flowed back to the oil pan. When you start the car, do n’t step on the throttle. Wait a few tens of seconds for the oil pump to pump the oil out.
