Vehicle maintenance is extremely important. It's very important for our vehicles to have maintenance every once in a while! As the saying goes, if you want a horse to run fast, you have to feed it! 2065438+At the beginning of May 2009, the car was lifted to 25,000 kilometers, and it was maintained at 5,000 kilometers every time. You usually add 95 # gasoline? Petrochemical, oil? The small gas station has not been added. No personal oil! Don't worry about oil! Later, I was also in trouble! Today, I will share with you the maintenance process of cleaning the throttle nozzle! It's not very dirty, and the carbon deposit is almost zero. After all, the quality of refueling at large gas stations is definitely no problem! I have seen a friend bring a new car back and keep adding small gas stations to refuel and add small oil! The new car is less than 7000 kilometers, and the car is dying of electricity, not to mention the whole car shaking and carbon deposition! That's equivalent to tens of thousands of kilometers of cars ... The later expenses are all raised at once? Think about why. ...

The dirty performance of the throttle nozzle makes the engine noisy, especially in low gear and low speed, the throttle is insensitive, the acceleration is uneven, and the idling jitter is easy, especially when starting, and there is a slight cylinder shortage in low gear and low speed upshift. ? Then how often should we clean it! I also asked in 4S stores and online, usually every 20,000 km to 40,000 km, but this is only a reference value. The specific cleaning cycle depends on personal car habits and the environment inside the car. I have been here for some time. I ran a long distance and cleaned up ahead of time! After cleaning in the 4s shop, I feel that the power of the car is much better … when accelerating, I feel obviously better than when I didn't clean it …
