Has anyone experienced idle speed being sometimes high and sometimes low? When I'm waiting at a traffic light, sometimes it's 7500, sometimes 9500, and this is without the AC on. The last two times, right after refueling, the idle speed was 9500. Not sure what's going on.

Toyota Yizhi, the air conditioning sometimes cools and sometimes doesn't. Pressing the AC button doesn't seem to help. Not sure what's going on.

Hey folks! Anyone else experiencing this with their Yizhi? What's the issue with the idle speed fluctuating when starting a cold car? Sometimes it hits 2000 RPM right after starting.

Is anyone else experiencing unstable idling with the new BRZ? Even without the AC on, whether the car is cold or warm, the gauge needle fluctuates noticeably.

If the Haima S5 manual transmission shakes when starting without giving gas and runs at idle speed, what could be the reason?

When driving at low speeds with the AC on, the car, which has over 30,000 kilometers, experiences significant vibrations. This is particularly noticeable when frequently reversing or making turns. The steering wheel, door handle, and seats all vibrate. Everything is normal when the AC is off. Sometimes, when idling with the AC on, there's a loud buzzing sound that feels overwhelming to the ears and head! I always use 95-octane fuel. Have you encountered this issue? How should it be addressed?

When your car is idling or waiting at a red light, can you hear a "ta-ta-ta" sound? I notice it every night after work when it's quiet, and it's really annoying. It's the same "ta-ta-ta" sound even if I rev the engine in neutral. The frequency of the sound is the same at different RPMs as when it's idling. Not sure what the issue is.

When you warm up your car or are idling at a red light, can you hear a "tatata" sound inside the car? Sometimes it's there, sometimes it's not. It's not the engine sound. Even if you press the accelerator a bit, the "tatata" sound frequency stays the same. Not sure what's causing it.

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.

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.
