Is it necessary to remove and clean the throttle for maintenance?

Simply put, it is not necessary to clean the throttle every time, unless the use environment is too bad, such as driving in a high dust and high pollution environment for a long time, then clean it simultaneously every time. There are many kinds of throttles, so it is generally recommended to go to a professional garage to find a professional master to clean them.

As for how to clean, here are a few points that can be supervised even by a professional master. First, it is necessary to use a special cleaning agent for the throttle valve, mainly to protect parts, and chemical oil cleaning is a bit corrosive; Second, if the carbon deposit is not so serious, don't take it apart for cleaning, especially when the new car has just entered the maintenance period. Mainly unnecessary, frequent disassembly is not good for parts. And some models can't be disassembled; Thirdly, if the car is old and the throttle has never been cleaned, the risk of cleaning is greater, because it is very likely that the throttle valve body has been irreversibly worn, which may lead to unstable idle speed and increased fuel consumption after cleaning, and finally only accessories can be replaced; Fourth, it is the problem of collocation. Many electronic throttles need computer matching. If it is a common model, it is generally not a big problem. These repair shops will know better.

Last but not least, a car with a clear throttle will be unstable at first, even if it is well matched. This is a normal phenomenon, so after a period of normal driving, it is beneficial to learn and adapt to the body computer system.
