What are the causes of engine shaking at idle?

The main causes of engine shaking at idle are as follows: 1. Dirty throttle body: Excessive dirt on the throttle valve reduces the intake air volume in the intake manifold. When the air intake fails to meet the normal air-fuel ratio, it causes engine shaking. 2. Excessive carbon deposits inside the engine: Prolonged use of the engine leads to excessive internal carbon buildup, resulting in engine shaking. 3. Faulty spark plugs or ignition coils: Failure to replace spark plugs for an extended period causes excessive electrode gap, affecting ignition timing. This not only causes engine shaking but also increases fuel consumption. 4. Clogged fuel lines or injectors: A dirty fuel filter causes unstable fuel pressure, poor injector atomization, and incomplete combustion. The above conditions will lead to engine shaking.

What happens if the fuel filter is not replaced for a long time?

The fuel filter, if not replaced for a long time, will have reduced filtering capacity and may become clogged, leading to difficulties in starting the car and idle shaking. Here is an introduction to the fuel filter: 1. It is mainly used to filter impurities in the gasoline to prevent them from entering the injection valve and cold start valve, ensuring the quality of gasoline flowing into the fuel system. 2. If not replaced for a long time, the contamination will become increasingly severe, potentially causing blockages, reducing fuel supply pressure, leading to insufficient fuel supply, decreased engine power, and issues such as difficulty starting, idle shaking, and poor acceleration. 3. Additionally, a clogged fuel filter can result in poor fuel atomization, causing an imbalance in the air-fuel mixture ratio and incomplete combustion, which generates carbon deposits. These carbon deposits can worsen the blockage of the three-way catalytic converter, pollute the spark plugs and front oxygen sensor, leading to excessive emissions and other faults. 4. Under normal driving conditions, it is recommended to replace the fuel filter every 30,000 kilometers; if the gasoline quality is poor, the replacement interval should be shortened appropriately, such as every 20,000 kilometers. Replacing the fuel filter is a complex operation, so it is advisable to have it done at a professional repair shop or 4S store.

How to Fold the Rearview Mirrors?

Different car models may have varying styles for rearview mirror adjustment, but the functions are generally similar. The specific adjustment methods are as follows: 1. Press the automatic folding button for the rearview mirrors or rotate the button to the automatic folding position, and both side mirrors will fold simultaneously. 2. Typically, the automatically folded mirrors will unfold automatically the next time the vehicle is started. 3. Manual adjustment by the driver is also possible. Whether it's an electric rearview mirror or a manual one, both can be folded manually. However, electric mirrors contain motors and reduction gears, so they should be handled gently to avoid damaging the gears.

Do You Need to Press the Clutch and Brake When Starting?

In actual driving situations, whether to press the brake or not when starting depends on the environment: 1. Starting on a flat road: Simply press the clutch without using the brake, controlling the speed with the clutch, and fully release the clutch after starting. 2. Starting on a slight slope: It is best to press the clutch while also pressing the brake to prevent the car from rolling backward or lurching forward. 3. Starting on a steep slope (uphill): You must press the brake, strictly following the steep slope starting procedure—slowly lift the clutch and gradually release the brake to start. If the slope is too steep, the handbrake and accelerator may also be needed.
