Does Volkswagen 3000 need computer matching after cleaning the injector?

Matching reset, that is, factory identification is restored. You don't have to match it. Let it adapt first. Turn the ignition switch on and off several times without starting the car. When driving, step on the accelerator to the end, then release it and repeat it several times. If it doesn't work after idling, go out and run again. If not, match it again. It can be removed or washed, saving time and effort, and can also clean up the carbon deposit in the combustion chamber. Some people think that old cars are dirty. As long as you don't add inferior gasoline, change the steam filter frequently and maintain it properly, there will be no problem with the nozzle. The old car only has a combustion chamber and intake and exhaust passages, and there is a lot of carbon on the valve. If you want to clean, the machine must be turned on. After a long time, the rubber sealing ring ages and hardens, and it is either broken or poorly sealed when it is removed. This kind of sealing ring is not sold separately, and it is quite difficult to find. Why bother?
