What Causes the Classic Focus to Shake During Acceleration?

Classic Focus shaking during acceleration can be attributed to the following reasons: 1. Damaged engine mounts: When the engine mounts are damaged, their noise and vibration reduction functions are compromised, especially noticeable during acceleration and deceleration with pronounced shaking and noise. 2. Unbalanced wheels: This can also lead to shaking during acceleration and may cause the steering wheel to vibrate. 3. Excessive throttle carbon buildup: Carbon deposits in the throttle can lead to various minor car issues, with acceleration shaking being one of them. 4. Faulty spark plugs: In the engine cylinders, the air-fuel mixture requires an electric spark to ignite. If the spark is weak or absent, it can lead to a misfire, disrupting the engine's balance and causing the vehicle to shake and produce noise. 5. Clutch slippage: Whether it's a manual transmission or a dual-clutch transmission, power is transmitted by clamping the clutch plates. When the clutch slips, it can cause the engine to shake as if in a semi-engaged state, or in severe cases, result in jerking or even stalling.

How Many Years Can You Take to Get a Driver's License?

According to the Ministry of Public Security Order No. 139 in 2016: The result of learning to drive and taking the driver's license test is called the Learning Driving Certificate, and its validity period is 3 years. All subjects must be completed within three years, otherwise it will become invalid. The time of the Learning Driving Certificate is calculated from the day of the subject one test. The specific time arrangement for the driver's license test is as follows: 1. Many places stipulate that the time for learning subject one is about 1 month. 2. After passing subject one, subject two naturally requires learning, and the stipulated time is about 20 days. In practice, many people take much longer than 20 days to learn subject two. 3. After passing subject two, the road test of subject three requires a certain amount of time for practice, and the stipulated time is about 10 days. 4. After passing subject three, you can take subject four 3 days later. Upon passing subject four, the driver's license will be issued on the spot.

How Long Does It Take for a Car to Be Considered a Stock Vehicle?

There is no specific time point or definition for a stock vehicle. Normally, a car goes through a certain period from production, assembly line completion, distribution by the general dealer, to the main warehouse and sub-distribution. Typically, a stock vehicle refers to a car that has remained unsold in the main warehouse for over a year. Additional Information: 1. Identifying a stock vehicle is a straightforward process. Compare the manufacturing date on the vehicle's nameplate with the production date on the certificate of conformity—both must match. Additionally, check if the VIN code and engine number on the certificate match those on the original vehicle. Nowadays, dealers do not conceal the status of stock vehicles, as the interconnected processes make it impossible to falsify. 2. For inspecting a stock vehicle that has been stored for over a year, examine the exterior for any discoloration of the paint, check the condition of the wiper blades and tires for signs of aging to determine whether it was stored indoors or outdoors. Inspect the engine compartment's pulley and the door/window seals for integrity. After turning off the engine, turn on the headlights for 10 minutes to check if the battery can start the vehicle normally and observe if the engine runs smoothly without abnormal vibrations to assess its performance.

What are the problems with flood-damaged cars?

After a car is submerged in water, it may cause mold and rust in the car's pipes, making them difficult to clean; the soft furnishings in the car may develop odors and mold; the lubricating oil in the four-wheel bearings and half-shafts may deteriorate; and electronic devices in the car, such as the electronic parking brake and audio system, may be damaged. Below is a detailed introduction: 1. Safety hazards: A water-damaged car is like a "time bomb" with numerous safety hazards. Issues like mold and rust in the intake pipes, odors from the furnishings, and damaged electronic devices are minor problems. A flood-damaged car may suddenly stall while driving on the highway, have ineffective brakes, or fail to deploy airbags in critical moments. 2. Reduced performance: After being submerged, some parts of the car may rust, shortening their lifespan. Not only are the repair costs high, but the safety performance is also compromised. For example, corrosion in the vehicle's wiring can lead to sudden stalling due to short circuits while driving, or even spontaneous combustion, with severe consequences.

What are the symptoms of a clogged fuel filter?

The symptoms of a clogged fuel filter are as follows: 1. Engine stalls easily. After the fuel filter is clogged, fuel delivery is affected, causing insufficient fuel supply to the engine. This results in noticeable jerking while driving or shifting gears, and the engine is prone to stalling at idle. 2. Reduced driving power. Due to poor fuel supply, the engine's power output decreases, leading to weak acceleration and reduced vehicle speed. 3. Engine shakes at idle. Moderate clogging of the fuel filter not only reduces the car's power but also causes the engine to shake at idle. The methods to address a clogged fuel filter are as follows: 1. First, conduct a preliminary analysis to determine if the jerking phenomenon is caused by a fuel system issue. If it is confirmed to be a fuel supply system problem, measure the pressure of the fuel supply system and the fuel pump. 2. Connect a fuel pressure gauge to the fuel line between the fuel pressure regulator and the fuel injector using a T-joint. Install the air filter, start the engine, and test the fuel supply system pressure under idle, medium-load, and high-load conditions. 3. Then, adjust the throttle opening. The reading on the fuel pressure gauge should change with the throttle opening, meaning the pressure value increases as the throttle opening widens.

How to Deal with Car Paint Peeling?

If the car paint is only slightly scratched, toothpaste can be used to repair the scratches. For deeper paint peeling, polishing and waxing can restore the paint. If the peeling area is large, then repainting is the only way to restore it. More detailed information is as follows: 1. In reality, car paint is not as fragile as one might think. It has excellent resistance to acid rain, high temperatures, UV rays, static electricity, dust, and corrosion. Repainting is only necessary in cases of severe scratches or traffic accidents, and it is relatively easy to repair if the primer is not damaged. 2. To provide comprehensive protection for your car, you can opt for a paint protection film (PPF). PPF is a thermoplastic polyurethane film (TPU) that contains UV-resistant polymers, is resistant to yellowing, and has superior toughness, wear resistance, and adhesion. It also provides impact resistance. Once applied, it isolates the car's paint from the air, protecting against acid rain and oxidation. Most importantly, it can resist scratches of varying degrees. Polishing removes a portion of the paint, but with the correct technique, typically only 1-2μm (modern car paint thickness usually ranges from 80-130μm) needs to be removed to achieve satisfactory results. However, some deeper scratches cannot be completely restored to perfection through polishing alone.

Why is the brake pedal higher than the accelerator?

Because the brake pedal requires a longer travel distance, it is designed to be higher to facilitate full depression of the brake pedal without changing the driver's seating posture. In contrast, the accelerator pedal is positioned lower. Here is a mnemonic for distinguishing between the brake and accelerator: 1. Left brake, right accelerator: Drivers should always remember that the left pedal is the brake and the right is the accelerator, forming a natural and firm concept. Over time, this will prevent mistakes. 2. Heel under the brake: Drivers should develop the habit of placing their heel directly below the brake pedal, allowing them to brake immediately in emergency situations.
