Bora 1.6 After cleaning the throttle nozzle, hit the air inlet of the first motor, and then change the air inlet. Why?

Due to excessive carbon deposition, the intake valve of your Bora car is not tightly closed. When cleaning gas and detergent enter the air inlet, the mixed gas in the air inlet branch pipe of the air inlet is too rich. After hitting the car, the intake valve was not closed properly, and the spark in the combustion chamber entered the intake port, causing deflagration. Because the volume of the air inlet is limited, it will explode. It is suggested that the next time the throttle inlet is cleaned, cold cleaning should be carried out or the flow in the pharmaceutical industry should be reduced. During the cleaning process, the throttle should be exploded every 3-5 minutes, and the speed should be increased to 3000 rpm. If the carbon deposit on the valve is to be thoroughly cleaned, it is recommended to use American MOLE No.3309 full-effect cleaning protective agent for fuel system.
