Do I have to clean the throttle every maintenance? How to clean it?

You need to look after the car when cleaning the throttle, not every maintenance. Usually 30 thousand kilometers to wash a can. Of course, for some specific models, the fuel consumption is high, and it may be necessary to clean the fuel in advance. The throttle valve is a routine maintenance part, and its disassembly is very simple. Generally, the negative electrode of the battery is disconnected, and the air inlet pipe can be removed with a wrench. After disassembly, you can spray a special cleaning agent. After cleaning, the throttle must be reset, otherwise the engine will automatically match after driving for a period of time. In fact, there is no need to clean the throttle of our car engine every time, because the dirt on the throttle of our car engine can't reach that fast.

I suggest cleaning the throttle circularly. Cleaning more than 30,000 kilometers as far as possible is the most cost-effective throttle and a better cleaning cycle. Simply put, you don't need to clean the accelerator every time you maintain it, unless the environment is too bad, such as driving in a dusty and polluted environment for a long time, then you need to clean it simultaneously every time you maintain it.

There are many kinds of throttles, so it is generally recommended to find a professional garage and a professional cleaner. As for how to clean, here are a few key points, that is, you can also supervise the cleaning, and you are afraid to find professional experts with special accelerator cleaning agents, mainly to protect parts, which is a bit corrosive to oil removal; If the carbon deposit is not too serious, don't disassemble and clean it, especially if the new car has just entered the maintenance period, which is mainly unnecessary. Frequent disassembly is not good for parts, and some models cannot be disassembled; If the car is old and the throttle has never been cleaned, then the risk of cleaning is greater, because it is likely that the throttle mechanism is irreversibly worn, which may lead to unstable idle speed and increased fuel consumption after cleaning, and finally only parts can be replaced; Many electronic throttles need computer matching.

If it is a normal model, there is no problem. These repair shops will know this better. Finally, after the throttle is cleared, the vehicle will start idling unsteadily, even if it is well matched. This is a normal phenomenon. After a period of normal driving, it is best to let the computer system of the body learn to adapt.
