What Causes Car Body Shaking During Idling?

2 Answers

Car body shaking during idling is mainly caused by severe engine carbon deposits, ignition system issues, unstable oil pressure, aging engine components, etc. Below is a detailed introduction to car shaking during idling: 1. Ignition System Failure: Every time the ignition system is used, the spark plugs will wear out. Long-term use will lead to severe motor wear, causing the spark plug gap to increase, making it difficult to generate an arc, which increases the misfire rate. Inconsistent power output will cause the car to shake during idling. 2. Unstable Oil Pressure: The most common issue in the fuel supply system usually occurs with the fuel injectors. Excessive carbon deposits on the fuel injectors affect the fuel injection volume. When the fuel injection volume is too high or too low, it can easily cause the oil pressure to be too high or too low, leading to shaking during idling.

Actually, body vibration at idle is quite common in vehicle usage, and I've encountered many similar issues. It's mainly caused by unstable engine operation. For example, a dirty throttle body leading to poor air intake, aging spark plugs affecting ignition efficiency, or clogged fuel injectors causing uneven fuel supply - these can all disrupt the engine's working rhythm. Also pay attention to the engine mounts, which are responsible for buffering engine vibrations; once they age and crack, vibrations get transmitted directly to the body. Another issue is carbon buildup, especially excessive carbon deposits in the combustion chamber and behind the valves - just like a person having difficulty breathing, this affects engine performance. If you notice vibration, I recommend first checking these four key points, especially for vehicles with over 100,000 kilometers on the odometer.

How to align the camshaft chain on a Sonata?

The following is the method for aligning the camshaft chain on a Sonata: 1. Locate the timing marks on the chain; the chain mark between the two camshafts is in the middle of the intake and exhaust. 2. Align the marks on the two camshaft gears. 3. After alignment, they should be at 180°. Symptoms of a damaged car camshaft are as follows: 1. During startup, the crankshaft may reverse, and backfire may occur in the intake manifold. 2. The car idles unevenly with severe shaking, similar to a misfiring cylinder; the car lacks acceleration and cannot move properly, with the engine speed exceeding 2500 rpm. 3. The vehicle exhibits high fuel consumption, excessive exhaust emissions, and black smoke from the exhaust pipe.

Where are the position lights located?

Position lights, also known as clearance lights, are the red lights located at the outermost left and right sides of a car's rear. At night, after turning on the car lights, if you step out and observe, you will see the red lights at the outermost left and right sides of the rear illuminated—these are the position lights. Content expansion: 1. Position lights are somewhat similar to the anti-collision lights installed at the wingtips of aircraft. They are primarily used during driving in conditions such as dusk, overcast days, or rainy and foggy weather to indicate the width and height of the vehicle. This helps other vehicles determine their relative positions and sizes during encounters or overtaking. Typically, the color of position lights is white at the front and red at the rear. 2. Position lights are also referred to as small car lights and have other names such as width indicator lights and evening driving lights. Position lights are installed at the highest points of the front and rear of the vehicle.

What are the maintenance items for a car at 80,000 kilometers?

At 80,000 kilometers, a major maintenance service should be performed, requiring a thorough inspection of the vehicle. In addition to the regular maintenance items such as engine oil and oil filter replacement, the air and cabin air filters, fuel filter, spark plugs, brake fluid, coolant, and transmission fluid should also be replaced. If some parts have been replaced during recent maintenance, their condition should be checked to determine if replacement is necessary. Additionally, the wear level of brake pads and tires should be inspected, as well as whether the rubber components in the chassis or other parts are aging or cracking. The car maintenance items include the following points: 1. Primary maintenance items for the vehicle: After completing the primary maintenance, the vehicle should be clean, connections should be secure, the three filters should be unobstructed, and there should be no leaks of oil, water, gas, or electricity. 2. Lubrication items for primary vehicle maintenance: Check the oil levels of the generator, transmission, rear axle, and steering gear, and add lubricating oil as required. Ensure all oil nozzles on the vehicle are complete and functional. 3. Inspection and tightening items for primary vehicle maintenance: Check the steering gear, tie rods, drag links, and the connection and tightness of all steering arms.

How to Open the Antifreeze Container Cap?

Here are the methods to open an antifreeze container cap: 1. Simply twist it counterclockwise to open. 2. Tap the bottom of the antifreeze container to release some air inside. 3. Use an awl to pry the antifreeze cap slightly to release air, making it easier to twist open. 4. Pour hot water over the antifreeze cap (only the cap) to create a gap between the cap and the container. 5. Drill a small hole in the container or cap to "vent" it, balancing the internal and external air pressure. Below are some precautions for antifreeze: 1. Choose an antifreeze that is compatible with rubber seal conduits. The antifreeze should not cause expansion, corrosion, or other adverse effects on rubber seal conduits. 2. Pay attention to its anti-corrosion properties. Products that haven’t undergone formal testing often have strong corrosive effects, which can damage the car’s cooling system. 3. Avoid mixing it with water.

Should the side window film of a car be applied on the inside or outside?

Automotive side window film should be applied on the inside. Here are the relevant details: 1. Applying the side window film on the interior side protects it from exposure to wind and rain, enhancing its anti-aging properties and thereby extending the film's lifespan. Additionally, the film is less susceptible to external disturbances during use, reducing the likelihood of scratches or damage, and preventing the edges from peeling. 2. The advantages of automotive window film include: (1) Heat and sun protection: The film effectively blocks a significant amount of heat generated by infrared rays. (2) UV protection. (3) Safety and explosion resistance, creating a private space. (4) Reducing air conditioning energy consumption, improving aesthetics, and preventing glare.
