Is it normal for CVT to step on the accelerator with stepless speed change, and the speed drops first and then rises?

There are three reasons for this:

1 engine cause (engine air intake system problem, air leakage, dirty throttle and air intake, unreasonable sensor signal; Ignition system problem, but when this problem occurs, it will also occur during acceleration, accompanied by this phenomenon);

2. Signal transmission problems (communication failure between engine and transmission, signal distortion such as gear and brake, etc.). , accompanied by shift shock);

3 transmission part failure (internal mechanical failure of transmission, increased load of other transmission parts, etc.). ). I hope the answer will help you who want to adopt it.
