Car engine shaking warning light illumination can be attributed to the following reasons: 1. Poor fuel quality leads to incomplete combustion, causing excessively high concentration of mixed gas in the cylinders which triggers the engine shaking warning light. 2. Faulty spark plugs, high-voltage wires or ignition coils. Malfunctioning ignition system or poor spark plug firing condition can activate the engine shaking warning light. 3. Aging rubber components in engine mounts and transmission mounts may cause the engine shaking warning light to illuminate. 4. Faulty intake pressure sensor. Insufficient fuel supply from the fuel pump or malfunctioning intake pressure sensor can also trigger the engine shaking warning light.

Can the car still be driven after abnormal engine shaking?

It is not advisable to drive the car after abnormal engine shaking. The causes of abnormal engine shaking include the following points: 1. A dirty throttle can cause engine shaking. 2. Faulty spark plugs can lead to rapid vehicle shaking. 3. If one cylinder of the engine is not working, it can also cause engine shaking. Additionally, the vehicle may shake during low-speed acceleration. 4. Aging rubber components inside the engine mounts and transmission mounts can result in engine shaking. The soft rubber connection between the engine and the frame may be damaged. The natural lifespan of rubber is 5 years, and the design life of engine mounts is 80,000 to 100,000 kilometers. Therefore, whether it is pure rubber or hydraulic mounts, issues of rubber aging or damage may arise, requiring inspection and replacement.

Where to Obtain the Motor Vehicle Inspection Compliance Label?

The collection of the motor vehicle inspection compliance label requires bringing the vehicle registration certificate, compulsory traffic insurance, and ID card to the vehicle management office or traffic police station to receive the annual inspection label for free. The procedure for obtaining the annual inspection sticker for exempted vehicles is as follows: 1. Vehicles exempt from inspection within 6 years, provided no major accidents have occurred, are exempt from on-site inspection. However, every two years, they must go to the vehicle management office to receive the annual inspection sticker and the green environmental protection sticker. At the time of inspection, bring your ID card, vehicle registration certificate, and the current valid compulsory traffic insurance policy to the vehicle management office for processing. 2. The annual inspection sticker and green environmental protection sticker for exempted vehicles are free of charge. But a copy of the vehicle registration certificate must be provided when collecting the stickers. Arrange your time reasonably; you can apply for the exempted inspection sticker 60 days in advance. Late applications will incur a fine of 200 yuan and 3 penalty points. 3. Before collection, check if the vehicle has any violation records.

What are the reasons why the Baojun 560 automatic transmission cannot engage gear?

Reasons why an automatic transmission car cannot engage gear include the gear lock being engaged, a dead battery, or a broken gear shift cable. Gear lock engaged: Some automatic transmission vehicles are equipped with a gear lock switch, primarily used to force gear shifting when the car has no power or to prevent rolling. Accidentally activating this switch can lock the gears. You can locate the "shiftlock" button near the gear shift lever to unlock it. Dead battery: A dead battery can also prevent gear engagement. Check if the car's lights and dashboard are functioning normally. If they are not working, it indicates the car is out of power, and simply recharging the battery will resolve the issue. Broken gear shift cable: A broken gear shift cable can also prevent the car from shifting gears, and replacing the gear shift cable will fix the problem. When the car cannot engage gear, it is best not to force the gear shift lever, as this may lead to a broken shift cable and cause mechanical damage to the transmission. If you are unable to shift gears normally while driving, find a safe place to stop the car before attempting to shift again to avoid danger. Additionally, always ensure the car is completely stopped before shifting into park (P) when parking.
