Why does the car shake and stall when the air conditioner is turned on?

When the air conditioner is turned on, the car shakes and stalls because the engine idle speed is not increased. The specific reasons are as follows: Automatic stalling at idle is mostly caused by issues with the throttle valve or idle control valve. Severe carbon buildup or component damage in these areas can trigger this fault, with insufficient air intake being the main cause. Solutions: If the car stalls when the accelerator is pressed at idle, the throttle valve, idle control valve, and other intake system components should be inspected first. Additionally, the fuel system should also be considered, including whether the fuel pump is damaged, whether the fuel passages are clear, whether the fuel injectors are clogged, and whether the fuel pressure is normal. The cause of this issue might also be related to problems with the spark plugs or ignition coils. Poor spark plug ignition quality or damaged ignition coils can be diagnosed through a spark test, but this requires the expertise of a professional automotive technician.

How much over the speed limit for a hazardous material vehicle results in 12 penalty points?

If a hazardous material vehicle exceeds the speed limit by more than 50%, it will result in a one-time deduction of 12 penalty points. Decline in the driver's ability to judge speed: When driving at high speeds, the driver not only fails to correctly judge the speed of their own vehicle but also underestimates the speed of pedestrians, non-motorized vehicles, and other motor vehicles. When overtaking another vehicle, they are prone to underestimating the speed and distance of oncoming vehicles, as well as the distance required to complete the overtaking maneuver. This often leads to delayed reactions, increasing the risk of collisions or side-swipe accidents. Decline in reaction ability: Speeding increases the frequency of overtaking and encountering other vehicles, reducing the safe following distance. The driver is overwhelmed by the rapid succession of external situations, consuming significant mental and physical energy. The constant shifting of attention can lead to fatigue and, over time, drowsiness, greatly increasing the likelihood of accidents.

How Long Does It Take to Practice Steering Wheel Control?

Steering wheel control generally takes about half an hour to an hour to practice. Correct hand positions for steering: Turning the steering wheel one full rotation equals 360 degrees, and a quarter turn equals 90 degrees. You can visualize the steering wheel as a clock. The proper hand positions are: left hand near the 9 o'clock position and right hand near the 3 o'clock position. If you want to turn 90 degrees beyond one full rotation, turn the wheel one full rotation plus an additional quarter turn. Steering techniques: Beginners practicing steering wheel control don't need to overthink the exact degrees of rotation. Just follow the principle: 'Turn as much as needed, return as much as turned; turn less, return less; turn slowly, return slowly; turn more, return more; turn quickly, return quickly.' As for how much to turn, you can judge by the steering wheel markings or directly adjust based on the direction of the car's front and body.

What is the difference between FE and TC transmission fluids?

The difference between FE and TC transmission fluids lies in their viscosity. FE has lower viscosity, making the oil thinner, which ensures smooth cold starts but may result in thinner oil film and poor lubrication during high-speed operation. TC has higher viscosity, making the oil thicker, which can make cold starts difficult but provides better oil film protection during high-speed operation. Hazards of not changing transmission fluid: 1. Damage to the transmission's shift control mechanism; 2. Abnormal wear of gears and clutch plates inside the transmission; 3. Impact on the normal operation of the transmission, leading to damage to the transmission valve body. Transmission fluid is not the same as engine oil. Although both serve a lubricating function, they have different roles and should not be confused. Difference: Engine oil is the lubricant for the engine system, possessing properties such as oxidation resistance, wear resistance, and corrosion prevention, while transmission fluid is primarily used to keep the gear system clean and extend the service life of internal transmission components. Due to the different structures and operating environments of the transmission and engine, transmission fluid cannot be used as engine oil, nor can engine oil be used as transmission fluid.

Why does a new car make noise when turning the steering wheel in place?

New car making noise when turning the steering wheel in place may be due to new car break-in, friction between the spring steel plate and the steering wheel, or issues with the shock absorber. New car break-in: If the new car hasn't been properly broken in, turning the steering wheel in place may produce noise. The noise will disappear after some use, so there's no need to worry in this case. Spring steel plate friction with the steering wheel: The sound of the spring steel plate for the horn wire transmission rubbing against the steering wheel usually comes from inside the car and is a rustling metal friction sound. The solution is to apply some lubricating oil at the friction point between the spring steel plate and the steering wheel. Shock absorber issue: If the noise is heard from outside the car when turning the steering wheel, it might be due to lack of lubrication in the shock absorber's plain bearing. Simply open the hood and listen to see if the sound is coming from the top of the shock absorber mount to confirm if it's from the plain bearing. If the plain bearing lacks oil, applying some grease can help. If the noise persists after greasing, replacement is the only option.
