Waiting at a traffic light, slow start, have to press the accelerator [angry]

Why does the start-stop function in the 2009 Smart cause the vehicle to stall? It usually happens when waiting at a red light. When the start-stop function is on and the light turns green, I find that the vehicle has already stalled, and I have to wait a moment before I can restart the vehicle.

Hello everyone, I'd like to ask something. When I cold start my car, the idle speed is quite high and when I release the brake, the power is strong and it just surges forward. But after driving for a few minutes or waiting at a few traffic lights, it starts to lose power. When I release the brake, it moves very slowly, and it only gets a bit better if I press the accelerator. It's a 2007 model with an automatic transmission.

I have a 2023 Jietu X90 Zilong Changsheng version. When starting and accelerating, the engine roars loudly. Is it the same for everyone? There's no engine noise when it's idling, but as soon as I press the accelerator to start, the engine sound is quite loud.

When I press the accelerator deeply, the car jerks, but it's fine with light acceleration. What's going on? It's a 2014 manual elite model.

Have any of you experienced a situation where the engine shakes violently when you release the brakes while waiting at a traffic light? What could be causing this?

Why doesn't the RX5 MAX Gaode Map have traffic light countdowns?

I have a 2017 New Santana, and occasionally it won't start. If I wait a while or press the gas pedal, it starts. Can someone explain what's going on?

Why isn't it turbocharged? With the WRX engine, acceleration would be faster. This acceleration is too slow.

I have a 2017 automatic model with 50,000 kilometers on it. Recently, I've noticed three particularly obvious issues: 1. When starting at traffic lights, even with light acceleration, I can hear the engine howling. The fuel consumption spikes to 19.9, the engine revs up to 2000 RPM, but the acceleration is very slow. 2. When driving home from work and going up the parking ramp, I often find that even with the gas pedal pressed, there's no power. The RPM goes up to 3000, and the fuel consumption also spikes. 3. Occasionally, when starting the car, it will shake and then stall by itself. Overall, driving at speeds between 0-40 is uncomfortable, but things improve above 60, especially on the highway. Acceleration and overtaking are fine at higher speeds. It's quite frustrating. Is anyone else experiencing the same issues?

There's a jerking sensation when starting at a traffic light. It didn't just start recently. Any good solutions?
