Is the accelerator cleaner useful?

The accelerator cleaner is harmless and is specially used to clean the accelerator: 1. Throttle is used to control air intake. When the throttle is dirty, the air intake will become smaller and the engine power will be insufficient; 2. Another is the disassembly-free cleaning of the throttle. Disassembly-free cleaning is a convenient device invented by lazy people, which sucks the engine intake manifold from the air inlet through vacuum. However, it's better to take it down and clean it, which will be cleaner. It should be noted that many vehicles now need computer matching after cleaning the throttle.
