Engine idle vibration is a common phenomenon, and there are seven possible causes for this vibration: 1. Unsuitable gasoline. 2. Insufficient ignition energy due to spark plug failure. 3. Air intake system leakage or low fuel pressure. 4. Poor atomization, leakage, or clogging of the fuel injector, or improper idle adjustment. 5. Malfunctioning idle control valve or exhaust gas valve. 6. ECU misjudgment caused by issues such as carbon buildup on valves and intake ports, piston and cylinder wear, or faulty coolant temperature sensors, leading to insufficient power output and vehicle vibration. 7. Aging engine components. Vehicle vibration can also be related to worn engine mounts. Engine mounts are essentially the shock absorption system of the engine, responsible for absorbing minor vibrations during operation. If the engine mounts fail, these vibrations can transfer to the steering wheel and the cabin, causing vibrations during idle.

Will the online system show the results if I didn't sign after the Subject 3 driving test?

In most cases, not signing doesn't matter. According to feedback from relevant trainees, failing to sign after completing Subject 3 generally won't affect the upload of test results. Signing on the test score sheet doesn't mean passing the exam: However, theoretically, whether you pass or fail the test, you need to collect the score sheet and sign it (electronic score sheets can also be signed). In practice, many trainees who know they didn't pass the test choose not to collect and sign the score sheet, leaving the test site directly. In most cases, not signing doesn't matter: According to feedback from relevant trainees, failing to sign after completing Subject 3 generally won't affect the upload of test results. The only possible impact is that you might not be able to schedule the Subject 4 test - this can be resolved by completing the signature later. Additionally, if signatures are incomplete, the driver's license cannot be issued, so staff will remind you to sign later even if you forget. To be safe, it's best to sign and confirm your scores after each test.

What are the 6 precautions for driving in snow?

Winter snow driving requires the following precautions: Pay attention to the driving environment: Observe the driving environment carefully to respond to unexpected situations. Check tires before driving: If the tires are severely worn, they need to be replaced promptly. Increase following distance: Rain and snow make the road slippery, increasing the following distance can prevent accidents caused by sudden braking of the vehicle ahead. Control your speed: It is best to drive at low speed in low gear. If the speed is too high and braking is not timely, the consequences will be very serious. Brake early and gently: Sudden braking can easily cause the vehicle to skid. If the vehicle does not have an ABS anti-lock braking system, the consequences will be more severe. Avoid stomping on the accelerator: Winter roads may be icy, reducing tire grip. Stomping on the accelerator can cause tire slippage, which can easily lead to traffic accidents.
