Why does the Ford Territory suddenly lose power and then accelerate again multiple times when normally accelerating to 60 km/h?

Is it normal for a 2015 model 2.0L automatic transmission car to have the RPM around 1300 at 60-70 km/h, and when slowing down for a turn then accelerating again, the RPM suddenly rises and acceleration is slow, with the RPM at 1600 to 1700 at 60 km/h and not dropping, and sometimes after turning off the engine and restarting it behaves normally?

Whose car would behave like this, suddenly losing power while accelerating and then gaining speed again?

What is the 0-100 km/h acceleration time for the G90?

While driving normally and making a U-turn, the gears suddenly started jumping. The engine didn't stall, but there was no power. The engine malfunction light came on, and the ECO indicator disappeared. After restarting, the car drove normally again, but the malfunction light remained on.

Why does the Ford Territory suddenly lose power and then accelerate again multiple times when normally accelerating to 60 km/h?

When starting the Jetour X90 Zilong, the throttle response is decent, and the power comes immediately. However, after reaching 70 km/h and releasing the throttle, if you want to accelerate again, there's a 1-second delay before the power suddenly kicks in. This isn't the same as getting power instantly when you press the throttle. What's going on here?

I have a 2023 JETOUR X90 Zilong. When driving at low speeds, if I press the accelerator, the car suddenly surges forward. However, after reaching 70 km/h, if I release the accelerator and then try to accelerate again, there's about a 2-second delay before the car suddenly surges forward. Is this throttle response delay a common issue?

When driving, sometimes when I press the accelerator, I feel a jerk, like there's suddenly no power, and then it's fine again. What's going on? Does anyone else have the same issue?
