What is the reason why the automatic car can't be lifted?

If an automatic car cannot be lifted at a higher speed, the following measures need to be taken:

First, use the automobile diagnostic computer to detect whether there is a fault code, and then repair it after troubleshooting.

Second, check whether the spark plug of the vehicle is ablated. Weak ignition energy will also cause the vehicle to be weak.

Third, check the air intake filter of the vehicle. The air is not smooth after being dirty, and the engine is stuffy without air.

Fourth, check the dirty degree of the throttle. Too dirty will lead to inaccurate throttle position signal and weak acceleration. Just clean the throttle:

1. Remove the throttle hose.

2. Open the throttle.

3. Clean with a brush.

4. Spray with detergent.

5. Replace the hose and it's done.
