Engine yellow light illumination with jerking sensation can be caused by oxygen sensor failure, intake issues, or fuel quality problems. Oxygen Sensor Failure: If the oxygen sensor is damaged or the sensor connector is damaged or loose, it can lead to a mixture that is too lean or too rich, triggering the malfunction indicator light. Solution: Visit a repair shop to service or replace the oxygen sensor. Fuel Quality Problems: Automobiles generally require fuel with specific octane ratings, and engine oil can be either semi-synthetic or fully synthetic. Manufacturers usually recommend which fuel octane rating and type of engine oil to use. If the owner fails to adhere to these recommendations over time, it can result in engine wear. Solution: Use the gasoline octane rating specified for the vehicle. Intake Issues: During combustion, the engine requires air intake. If the car's air filter is dirty and not cleaned regularly, it can affect the vehicle's air intake. Prolonged neglect can lead to clogging, and in severe cases, it may cause the engine malfunction light to illuminate. Solution: Regularly clean the air filter.

Which is more harmful to a car: exposure to direct sunlight or parking under a tree?

When it comes to parking a car under direct sunlight or under a tree, parking under a tree is relatively better than exposure to sunlight. First of all, leaving a car parked outdoors all year round is certainly not ideal. Exposure to wind, sun, and rain can cause significant damage to the car over time. Paint aging, cracking, loss of body shine, and rusting of metal components are some of the damages that may occur. Below are the relevant details: 1. Parking under high-temperature exposure: Many car surface paints are quite thin, and prolonged exposure to sunlight can accelerate paint aging and fading, causing the car body to lose its luster, affecting its appearance, and even leading to paint cracking, bulging, or peeling, which shortens the paint's lifespan. Additionally, many car interiors are made of plastic, with components glued together. Under high-temperature exposure, harmful gases like formaldehyde can be released, posing health risks to humans. Moreover, these materials can soften and deform easily. Car seats, usually made of leather, can harden and deteriorate in touch under high temperatures. 2. Parking under a tree: While parking under a tree can avoid direct sunlight, it comes with its own set of problems, such as bird droppings. Bird droppings are acidic and highly corrosive to car paint. Additionally, falling branches, leaves, tree sap, and fruits can dirty the car and affect its appearance. There is also the risk of branches breaking and falling onto the car. In fact, there is a way to protect your car from the summer sun without worrying about getting dirty under a tree: using a car cover. A car cover can provide sun protection, as well as shield against dust, rain, and bird droppings.

What to Do When Car Key is Hard to Insert or Remove?

If the car key is difficult to insert or remove, you can crush pencil lead and apply it into the keyhole. The specific steps are as follows: 1. Use a knife to scrape the pencil lead into powder form. 2. Put the powdered pencil lead into a plastic tube, then blow it into the keyhole using the tube. 3. Repeat the above steps until the car key can be inserted and removed normally. If you don't have a plastic tube, you can also put the powdered lead on the key and insert it directly to let it enter the lock. Compared to traditional mechanical keys, smart keys are now widely used. The smart key system can automatically unlock and lock car doors. The smart key mainly consists of a signal transmitter, remote central locking control module, and driving authorization control module.
