The classic Focus also has a throttle effect of 2.3.

Hello, I am from Jinan. Among many models, Fox has the highest requirement for throttle. A little dirty makes it difficult to get a taxi or poor power. It is generally recommended to wash the throttle valve once at 65438+100000. We often wash Fox's. There is no way. This car is designed like this. If you insist on not washing the throttle valve, it will easily lead to ignition difficulties, poor acceleration, poor power and increased fuel consumption. More seriously, it will cause a large amount of carbon deposition in the engine combustion chamber and affect the normal service life of the car. I do after-sales service of automobiles, and I hope it will help you.
