Buick Yinglang feels frustrated when stepping on the accelerator, so it is necessary to clean the carbon deposit on the throttle, check whether the fuel injection nozzle is blocked and check the spark plug.
 If the gear does not fall down after going up from high speed to low speed, the fuel filler valve will shake, and the gear should be changed in time.
 If the seat also shakes, it may be that the four-wheel suspension support is too hard, and the tire vibration is transmitted to the chassis, which causes the vehicle resonance, and the rubber products of the suspension support need to be replaced.
 If it is a simple acceleration bump, it is generally caused by ignition coil failure and spark plug failure, especially after the hot car, the acceleration bump will gradually disappear, that is, the initial acceleration bump.
