1. There must be something wrong with the oil. 2. Is the throttle dirty? Have you checked the oil circuit? 3, engine jitter, noise, whether to check the engine foot glue. 4. If there is still a problem, drive to the 4S shop and let the professional master drive on the road. We have more than 100 yuan here. Check what is wrong with the car and it will come out as soon as it is checked. Don't fix it in the shop outside.
