1 1, Mondeo won, and there was an abnormal noise when killing in the 2.0t direction.

First, the dead direction will lead to an increase in the pressure load of the booster pump, resulting in an abnormal sound of "goo goo", which will not ring after a little return; Second, there is still a feeling of abnormal noise or a slight jump in direction, which should be the noise caused by tire sideslip. The reason is that the toe-in or inclination angle of the front wheel is too large, so it is corrected by four-wheel alignment; Third, clean the throttle valve when there is obvious peristalsis in the general direction of the car.
