Does anyone with a 2008 model experience the same issue? In the hot summer, whether idling or driving, the blower occasionally runs at a high horsepower, making a loud noise. It's more noticeable when idling and parked.

Dear fellow car enthusiasts, I've been experiencing an issue with my 2008 Yaris where it occasionally stalls while idling at a red light. After restarting, it might stall again at the next red light. This happens two or three times, but then it runs fine afterwards. There are no error codes on the dashboard, and when I took it to the repair shop, the diagnostics showed everything was normal. Does anyone know what the problem might be?

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.

I have a 2007 Touran, automatic 1.8t. It jerks noticeably during acceleration. When idling while parked, the RPM intermittently drops by 100-200, and the car lights dim. What should I do? (I've previously cleaned the fuel injectors and throttle body.)

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?

Is anyone familiar with solving the issue of idle speed occasionally rising to 2000 RPM and then dropping back down on a stock MG HS? It's particularly noticeable at low speeds.

When driving a 206 with a 1.6 automatic transmission, whether on the highway or at low speeds, the engine noise becomes very loud once the RPM exceeds 2800. There's a buzzing sound inside the cabin that is even louder than the wind noise—it's really loud! When the car is idling after warming up, there's a noticeable vibration if you hold the steering wheel or sit in the seat. What could be causing this? Looking for guidance from experts!

Four years, 40,000 km, 1.5T F56. There's noticeable shaking and noise at idle. Is this common for everyone? I bought it second-hand, so I'm not sure how it was when new. Also, when driving on rough roads, there's noise from the left and right side windows. When the windows are down, there's no noise. I suspect it might be the frameless doors causing the glass to rub against the body. Does anyone else experience this?

I need some advice from experts: I have a 2013 1.4T Touran. Recently, the engine occasionally makes a loud noise after starting, and the idle speed is over 1100. But after turning off and restarting, the engine sounds normal, and the idle speed is around 700, back to normal. What could be the issue?

When idling in place, the tachometer occasionally fluctuates slightly. What could be the issue, fellow car enthusiasts? On a flat road, when driving in first gear at idle, there is a noticeable jerk. The jerkiness becomes more pronounced when the air conditioning is turned on.
