My swift drove too hard last night. Now I don't know why it stays at 1500 to 2000 rpm as soon as it starts. What is this?

If the weather is cold, it is possible for the cold car to start and the speed to rise to 1500-2000. That doesn't mean there is something wrong with your car. I used to drive a German car, and I consulted several 4s shops, and the answer was yes. Because in the previous EFI car, although the engine was EFI, the throttle was mechanical, which is also commonly known as the cable throttle. Now, in order to meet the national 4 environmental protection standard, most cars use electronic throttle, which means that the throttle is also controlled by the computer, so when the cold car starts, the computer will automatically adjust the throttle opening according to the engine temperature as soon as possible. In the process of high-speed preheating, the precise response of the cable throttle is definitely not as accurate as that of the electronic throttle, so there will be a high speed of 2000 rpm, and most electronic throttles are around 1200. In fact, the ultimate goal is to make the vehicle reach the normal working temperature as soon as possible, and your speed is still within the normal range.
