2.4 Why does Accord get dirty easily?

The air inlet filter is not well filtered and the surrounding environment is dusty.

There are many reasons for dirty throttle, such as oil quality, air quality, air filter replacement cycle, driving habits and so on. The normal throttle opening should be less than 2.4%, and it should be cleaned if it is greater than this number.

Generally, the cleaning method is no disassembly and no cleaning, but it should be noted that it is not recommended to spray cleaning solution directly into the throttle, which may damage the electronic throttle.
