The new car ran 4000 kilometers. You didn't need to produce oil at first, but now it will turn off if you don't step on it, and it will turn off if you don't shift gears in the middle. What happened?

The automobile has the function of automatic refueling at the start, which requires multiple sensors and actuators. In this case, most of the reasons are that the throttle is dirty. Because it is a new car, you are often in a state of low speed and small throttle when driving, and it is easy to get the throttle dirty. I suggest you go to a 4S shop or a bigger repair shop to clean the throttle valve. It should be noted that if you want to save some money, you can find a smaller repair shop. Most importantly, after cleaning, you must match the program with the computer. Some small repair shops don't have computers, just help you clean them, and then there will be high idle speed and automatic refueling.
