It is very expensive for Jianghuai He Yue to clean the throttle. What is the reason?

Spark plugs are different, so it is recommended to change back to the original factory, which is cheaper and shorter, so the ignition center point in the cylinder will be different, which may lead to incomplete combustion. This has nothing to do with whether the spark plug is good or not and whether the ignition intensity is strong or not. In addition, after cleaning the oil circuit, it should be equipped. If there is no match, the fuel correction will still run according to the previous procedure. After the original fouling, the computer increased the fuel injection pulse width. It will take a long time to control according to this now.
