What's wrong with the new Regal throttle of Shanghai GM Buick?

The new car uses an electronic throttle, that is, there is no cable and there is a sensor on the throttle. Generally speaking, this kind of throttle is very good, because it has no resistance, so I suggest you check whether there is anything to stop the throttle from returning. For example, if there is something wrong with the mat car, find the car master. 4S shop professional technician, 10 minutes to solve.
