After cleaning the throttle, the throttle is stuffy and the acceleration is slow.

Excuse me, do you want to ask "what is the slow acceleration after the throttle is cleaned?" The causes of this problem are: improper cleaning agent, improper cleaning method and damaged ignition system.

1. Excessive use of cleaning agent: the mixture is too rich and the combustion is insufficient. This problem can be solved by itself after driving for a period of time.

2. Improper cleaning method: it will damage the ignition system and sometimes even damage the engine parts.

3. Ignition system damage: When the spark plug is about to be replaced, improper cleaning will make the engine easy to explode and damage the ignition system to some extent.
