Reasons why the car feels sluggish and stuffy: 1. Air intake pipe leakage causing excessively lean air-fuel mixture; 2. Weak high-voltage spark due to faulty spark plugs, igniters or high-voltage wires; 3. Poor operation of the exhaust gas recirculation system; 4. Malfunctions in components such as the air flow meter, intake manifold absolute pressure sensor, or throttle position sensor; 5. Turbocharging system failure; 6. Carbon buildup in cylinders, throttle, spark plugs, or intake pipes. If the car feels sluggish and you notice obvious steering wheel or body vibration when the vehicle is stationary, this indicates that at least one cylinder in the engine is not operating properly or has shut down.

Where to Place the Inspection Sticker?

The inspection sticker should be placed on the upper right corner of the front windshield. Vehicles are required to display two stickers: the motor vehicle inspection sticker and the compulsory traffic insurance sticker, both of which should be affixed to the upper right corner of the front windshield. According to relevant regulations, if a motor vehicle driven on the road does not display a license plate, inspection sticker, insurance sticker, or if the driver fails to carry the vehicle registration certificate and driver's license, the traffic management department is required to impound the vehicle and notify the party to provide the corresponding documents, stickers, or complete the necessary procedures. The license plate should be displayed at the designated positions on the front and rear of the vehicle, ensuring clarity and completeness. Heavy-duty and medium-duty trucks, their trailers, tractors, and their trailers should have enlarged license numbers painted on the rear of the body or cargo compartment, with the characters being neat and clearly visible.

How to Clean a Car Air Conditioner?

Methods for cleaning a car air conditioner: 1. Turn off the car engine and the air conditioner switch, and locate the position of the car air conditioner; 2. Prepare car-specific cleaning agent and a cloth, then open the air conditioner protective cover; 3. Locate the position of the air filter. Most air filters are located inside the glove box, so the glove box needs to be removed first to access the air filter. Open the glove box and squeeze the plastic on both sides to remove the glove box; 4. Clean the air conditioner ducts. Set the air conditioner to external circulation, then turn the fan to maximum speed. Spray the air conditioner cleaning agent into the position where the air filter was removed. Under suction, the cleaning agent will enter the air conditioner ducts; 5. Let the air conditioner system run for about 10 minutes, and the dirt will flow out from the duct system located at the chassis; 6. After removing the filter, clean the dust thoroughly, and then you can turn the car air conditioner back on for use.

What is the difference between Subject 1 and Subject 4?

The main differences between Subject 1 and Subject 4 include: the number of test questions, question types, distribution of exam content, and focus areas. The information is based on the "Regulations on the Application and Use of Motor Vehicle Driving Licenses". Number of test questions: The most obvious difference between Subject 1 and Subject 4 is the number of test questions. Subject 1 has 100 questions, while Subject 4 only has 50 questions. In Subject 1, the test will automatically submit if more than 10 questions are answered incorrectly, whereas in Subject 4, the test will automatically submit if more than 6 questions are answered incorrectly. Question types: Subject 1 consists of 100 questions, each worth 1 point, with a total test duration of 45 minutes. The question types are true/false and single-choice questions, with a full score of 100. Subject 4 consists of 50 questions, each worth 2 points, with a test duration of 45 minutes. The questions are primarily presented in the form of case studies, images, animations, etc., and include true/false, single-choice, and multiple-choice questions, with a full score of 100. Focus areas: Subject 1 mainly tests basic knowledge of road driving, while Subject 4 focuses on safe and civilized driving knowledge. It can be understood this way: Subject 1 tests how to drive, while Subject 4 tests how to drive safely. Although the difference is just two words ("safe"), the focus is entirely different. Distribution of exam content: Subject 1 exam content breakdown: 20% on driving license and motor vehicle regulations; 25% on road traffic conditions and rules; 25% on traffic violations and penalties; 10% on road traffic accident handling regulations; 10% on basic knowledge of motor vehicles; and 10% on local regulations. Subject 4 exam content breakdown: 20% on safe driving knowledge; 18% on civilized driving knowledge; 8% on the comprehensive application of road traffic signals in traffic scenarios; 16% on safe driving knowledge under adverse weather and complex road conditions; 12% on emergency avoidance knowledge; 6% on typical accident case analysis; 10% on traffic accident rescue and common hazardous chemical handling knowledge; and 10% on local test questions. There is no limit to the number of attempts for Subject 1 and Subject 4 in the driving test. If you fail, you can reschedule the test. Each scheduled test offers two attempts. If both attempts are failed, you can only retake the test until you pass. Both Subject 1 and Subject 4 are theoretical exams and are part of the motor vehicle driving license assessment. The driving test consists of three subjects: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the road traffic safety laws, regulations, and related knowledge exam; Subject 2 refers to the field driving skills exam; and Subject 3 is divided into two parts: road driving skills and safe and civilized driving knowledge exam. The safe and civilized driving knowledge exam is conducted after Subject 3, so it is commonly referred to as Subject 4. However, in official terms (i.e., the Ministry of Public Security's Order No. 123), there is no mention of Subject 4.

What are the steps for starting an automatic transmission car on a slope?

Press the button on the handbrake with your right hand but do not release it yet, slowly release the foot brake, move your right foot to the accelerator pedal, at this point the car is still held by the handbrake, gradually press the accelerator, and when you feel the car start to move forward, release the handbrake and continue to accelerate. Some cars have a hill-start assist function, which eliminates the need to control the handbrake during start-up, as the car will automatically release the handbrake at the appropriate time, making the operation simpler.
