What is the reason why sagitar 1.4t automatic transmission and luxury car suddenly appear forward or shake when driving?

From your description alone, I feel that the throttle is dirty. Just clean it up (Note: Cleaning the throttle is a very simple job. You have to charge more than 100 for manual work in the 4S shop, and 10 is enough for the outside shop. )

In addition, if it's not the throttle, consider whether you are unfamiliar with the performance of the car. For example, at what speed does turbocharging intervene? The sudden intervention of turbocharging will definitely speed up the car. As for shaking, I don't know how to shake. The accelerator is accelerating, and automatic gear shifting may have a sense of frustration. If you feel fast, the fuel truck will suddenly shake. I don't know about you.
