When the engine speed suddenly increases, it indicates a mismatch with the actual power output, which could be due to a throttle body malfunction. It is recommended to visit a 4S shop for inspection. Relevant information about idling is as follows: 1. Introduction: Idling is an operating condition of a car, referring to the engine running in neutral gear. The engine speed during idling is called the idle speed. The idle speed can be adjusted by modifying the throttle opening size, among other methods. Idling means the engine is "producing power without doing work." 2. Driving idle: When the car is in gear, without pressing the accelerator pedal or releasing it during driving, maintaining the minimum throttle opening, the engine speed matches the parking idle speed. This state is referred to as driving idle.

How to Deal with Clogged Sunroof Drainage in a Bora?

You can use an air pump gun, aiming at the drainage holes of the two front drainage pipes inside the sunroof, and use high-pressure airflow to clear the drainage pipes. Here is an introduction to the related content: 1. Sunroof: The left and right sides of the sunroof are two sliding rails that ensure the sunroof slides back and forth. At the front left and right corners of the sliding rails are the drainage holes of the sunroof. 2. Common issues: Clogged or broken drainage pipes can result in water leaking from the sunroof seam and dripping into the interior. If broken, it can also cause water leakage in the car's A-pillar and C-pillar. Another issue is the aging of the sunroof's sealing strip, leading to water leakage from the sunroof.

What Causes the Metallic Friction Sound When Pressing the Accelerator?

Pressing the accelerator and hearing a metallic friction sound is usually caused by carbon buildup in the intake system. It is recommended to visit a repair shop for cleaning. Below is an introduction to related car noise issues: 1. Car Half-Shaft Problem: Under long-term torsional fatigue and impact forces, the car's half-shaft is prone to bending, twisting, breaking, or wear and tear on the spline teeth. This can cause the car to shake rhythmically when accelerating within a certain speed range, accompanied by noise. The shaking disappears or lessens when the accelerator is released. 2. Loose Engine Belt: A slipping belt can produce abnormal noise. Once the belt slips, the resulting friction and heat can cause the belt to stretch further, worsening the slippage and creating a vicious cycle. In this case, it is necessary to visit a repair shop to adjust the belt.

Does Crossing the Stop Line with Front Wheels Count as Running a Red Light?

Crossing the stop line with front wheels during a red light does not count as running a red light. Running a red light refers to the act of a motor vehicle violating traffic signal instructions by crossing the stop line and continuing to drive when the red light is on and prohibits passage. Determining a red light violation requires at least three pieces of photographic evidence: the vehicle has not left the stop line when the red light is on; the vehicle has passed the intersection when the red light is on; the vehicle has crossed the line and continued to move forward when the red light is on. Article 26 of the "Road Traffic Safety Law": Traffic signals consist of red, green, and yellow lights. The red light indicates prohibition of passage, the green light indicates permission to pass, and the yellow light indicates a warning. Article 44: Motor vehicles passing through intersections shall do so in accordance with traffic signals, traffic signs, traffic markings, or the command of traffic police. Article 2, Paragraph 1, Subparagraph 2 of the "Scoring Standards for Road Traffic Safety Violations" stipulates that driving a motor vehicle in violation of road traffic signals will result in a deduction of 6 points per violation. Ways to avoid running a red light: When there is an arrow signal light, follow the arrow light; otherwise, follow the circular light; When the red light is on, the front of the vehicle must not cross the stop line; When the yellow light is on, the front of the vehicle must not cross the stop line; When the green light just flashes, if the distance is close and the speed is fast, you should pass through, as it may be impossible to stop in time and you might cross the stop line; if the distance is far, the speed is slow, or the intersection is congested, you should stop; When driving in the city, develop the habit of looking for traffic lights whenever you see a crosswalk or stop line and approach an intersection.
