What is the harm of cleaning the throttle?

Cleaning the throttle itself is beneficial. Throttle carbon deposition will affect the intake state, and in severe cases, engine jitter and unstable idle speed will occur. However, a special cleaner is usually used to clean the throttle valve. After all, this chemical is different from the composition of gasoline itself, combining the carbon deposited after clean dissolution. Therefore, after the gasoline is mixed and burned, the incompletely burned components will cause additional burden to the three-way catalysis, so sometimes the exhaust pipe smoke will be very heavy when cleaning the throttle. However, this amount is very small and the impact is relatively small. In particular, the composition of professional accelerator cleaner will consider this problem, and safety will be considered in the selection of raw materials. So don't worry too much.
