How is it that the car stops running and the acceleration is weak after cleaning the throttle?

The original fault may be that the air intake system is not clean (too much carbon deposit in the throttle valve leads to insufficient air intake, and it is easy to turn off when the load is too large during driving, accompanied by a fault of low idle speed). If the problem is solved after cleaning, it means that it is really dirty.

Generally speaking, the acceleration after cleaning is weak for the following reasons:

1 When cleaning, the cleaning agent is sprayed too much, resulting in the mixture being too rich and the combustion being insufficient. This problem will solve itself after a period of driving/blowing (in a short time);

2 The quality of the cleaning agent used is poor/the cleaning method is improper (sometimes the throttle valve is cleaned with an air inlet, an oil circuit, a three-way catalytic converter, etc. ) it is very easy to cause abnormal damage to the engine and damage (blockage) of the three-way catalyst;

3 Check the ignition system (spark plug). Sometimes when the spark plug is about to be replaced, the cleaning agent is not properly cleaned/the quality of the cleaning agent is not good (the engine is easy to explode due to improper cleaning, which will damage the ignition system to a certain extent, and sometimes even damage the mechanical parts of the engine). I hope the answer will help you who want to adopt it.
