Car cleaning agent is sprayed on the accelerator.

At first, it was because of the carburetor cleaner that I was shivering with cold, so it was good to touch the car. If the hose is stuck at the valve, it may lead to unstable idle speed and cylinder loss. If there is unstable idle speed or cylinder shortage after parking for a period of time or later, it should be removed for treatment. If you don't take it out, it depends on the opportunity.
