Does Xintianyi need to clean the throttle and injector at this time?

Basically no need to wash. The purpose of cleaning is to remove carbon deposit and/or coking. As far as 13000 km is concerned, it is generally mild and will not affect the power and fuel consumption of the engine. Because the quality of oil products is basically guaranteed now, as long as you maintain good driving habits, there is no need to spend this money. You can lock it in a low gear, then run it with heavy oil for a few minutes, and keep the engine at a high speed, 4500 to 5500, so that high-speed air intake and strong fuel injection can also play a cleaning role, and there are no side effects.

Although car maintenance is important, it doesn't mean that the more you do, the better. Just like people don't have to take medicine if they are not sick. If something goes wrong, repair it, because the car will definitely be repaired in a certain time. Some car owners will cause idle vibration after cleaning the nozzle, so it is better to clean it carefully.
