How to Fix a Motorcycle Gear Lever That Doesn't Spring Back?

Where is the problem if the idle speed remains unchanged when the air conditioner is turned on?

There are several reasons for unstable idle speed when the air conditioner is turned on: 1. Engine control logic error: Unable to receive the signal that the air conditioner is turned on. When unable to determine whether the air conditioner is turned on, the engine control unit (ECU) will mistakenly assume it is a temporary high load and attempt to increase the speed to offset the resistance at idle. 2. Air conditioner control circuit error: Unable to send the signal that the air conditioner is turned on. Similar to the first point, because the air conditioner's on/off status cannot be determined, the ECU will continuously adjust the idle speed, resulting in unstable idle. 3. Air conditioner circuit failure: Causes intermittent operation of the air conditioner. When the air conditioner is not working, the air conditioner compressor belt is idling without load, so it will not affect the engine load. The intermittent operation of the air conditioner compressor causes the engine to continuously adjust the idle speed, resulting in unstable idle.

Do not open the sunroof on bumpy roads to avoid excessive vibration that may cause the window track to deform. 2. Avoid using a high-pressure water gun to directly spray the sealing ring when washing the car, as this may deform the sealing ring. 3. Clean the drainage holes and grooves of dust and leaves in time to prevent clogging of the drainage holes or reduced performance of the sealing ring. 4. Regularly apply lubricating oil to reduce wear on the window track and extend the life of the sunroof.

What Should Be Noted for Safe Driving?

Here are the precautions for safe driving: 1. Do not forcefully press the accelerator pedal before the engine coolant low-temperature warning light goes off, as insufficient heating can easily cause abnormal combustion of unburned gas and damage the three-way catalytic converter. 2. Before driving, always ensure that all doors are properly closed. Otherwise, doors may suddenly open during driving, leading to serious accidents. If any door is not securely closed, a door ajar warning will appear on the dashboard. 3. When snow or fallen leaves accumulate at the air intake under the lower edge of the front windshield, they should be promptly removed. Otherwise, fresh air cannot be drawn in, resulting in insufficient ventilation inside the vehicle. When it rains, the temperature inside the car rises, causing fog to form on the window glass and impairing the driver's visibility.

Will the ABS Anti-lock Braking System Increase Braking Distance?

ABS anti-lock braking system will shorten the braking distance. Functions of ABS: The anti-lock braking system can improve the safety factor of emergency braking while driving. In other words, for vehicles without ABS, when emergency braking is applied in critical situations, the tires are prone to lock up, meaning the steering wheel cannot be turned, thereby increasing the risk factor and potentially leading to severe consequences. Precautions for using ABS: During ABS braking, the rapid retraction and release actions of the brake calipers will frequently compress high-pressure brake fluid, producing noticeable noise, and the brake pedal may vibrate and push back against the foot. Do not be disturbed by these phenomena while driving. In emergency situations, use ABS braking without hesitation, firmly pressing the brake pedal all the way down and not releasing it.

How Significant Are the Effects After Repairing a Flood-Damaged New Car?

After being repaired, a flood-damaged new car can still have significant effects because, to some extent, flood-damaged vehicles can be restored, but even after repair, there are serious hidden dangers. Related information: 1. Reasons: The danger coefficient is very high for motor vehicles whose bottom components have been in prolonged contact with water, as the circuits are prone to short circuits, fires, and other accidents. Even after disassembly and drying, faults may still occur, and they cannot be completely repaired. 2. Expansion: If a motor vehicle is submerged in water, it can easily cause the body components to rust, shortening the service life and reducing safety performance. For example, a water-damaged vehicle can lead to corrosion and rusting of the wires, causing the vehicle to suddenly stall or self-ignite due to a short circuit while driving, with unimaginable consequences.
