Does anyone experience a situation where, while driving a manual transmission car at high speed, the RPM suddenly goes up but the speed remains the same?

Peugeot 206, 1.6L, automatic/manual transmission, 2006 model. The acceleration is very slow, and when you give it more gas, the RPM goes up, but the speed doesn't catch up. What's going on? Can any experts help explain this? Thanks!

Is there any other Coaster owner experiencing the same issue where the engine RPM fluctuates up and down while coasting in neutral?

The temperature is around minus three degrees, and suddenly today the gear shifting is very slow. It used to shift at around 2000 RPM, but today it goes up to 3000 RPM. The engine is making a humming noise. 😵‍💫 Do any other T-Cross owners experience this situation?

When starting a cold car, the RPM goes up to 2000 and then drops to 1500 but doesn't go any lower. The high idle speed is causing high fuel consumption, 20 liters for 300 kilometers! The idle speed is too high, and so is the fuel consumption. Can any experts provide a solution? 🙏

I've been driving a Suzuki SX4 for over ten years, and now the fuel consumption is higher than before. When I press the accelerator, the RPM goes up, but the speed doesn't increase. I've changed the transmission oil, cleared the engine carbon deposits, and worked on the throttle and fuel injectors, but the RPM is still high while acceleration is slow. Are there any fellow car owners who have experienced similar issues?

Car enthusiasts: Sometimes when driving a small car, the D gear won't shift up. The RPM suddenly goes up, but the gear doesn't match. What could be the reason?

After refueling my Jetta VS7 at the gas station, the idle speed tends to be high, around 1000 RPM. Then, during driving, the speed fluctuates. After driving for about ten kilometers, the idle speed returns to normal. Alternatively, if I turn off the engine and restart it, the idle speed also normalizes. I've tested this each time I refuel, and it's always the same situation.

What's the RPM for your manual transmission car at 120 km/h? Mine goes straight up to 3400 RPM! [Shocked]

Hello everyone, when driving an automatic Nissan Sunny, what's the situation when I brake and then accelerate, the RPM goes high but the car doesn't move? This often happens when turning as well, the RPM is high but it just doesn't go.
