Do you have to clean the nozzle and oil circuit when cleaning the throttle?

If your car has problems such as engine jitter, knocking, unstable idle speed and poor acceleration, it's time to clean it. But if you think there is nothing wrong with your car, and there are no problems such as unstable idle speed, weakness and fuel consumption, then you'd better not wash it. If the engine is all right, you'd better not disassemble it. Tearing it down will leave future trouble.

Adding gasoline additives to gasoline has a cleaning effect. Adding it can clean the nozzle and throttle, but there are many brands of this additive. I think it's best to go to the 4s shop for consultation. If you want to add, add a better one.

The advantages of cleaning injector and throttle oil are cleaning carbon deposit, improving intake and injection accuracy, improving fuel efficiency and prolonging engine life. The advantage is that the engine sounds good, the fuel consumption is reduced and the exhaust gas is reduced.
