How to Determine When the Throttle Body Needs Cleaning?

When experiencing sluggish acceleration, increased engine noise, severe cases may exhibit unstable idling and engine vibration, these are indicators that the throttle body may need cleaning. Below is more information about the throttle body: 1. Precautions for throttle body maintenance: (1) Avoid using highly corrosive cleaning agents. (2) Develop proper driving habits and refrain from using low-quality gasoline. 2. Definition of throttle body: The throttle body is a controllable valve that regulates air intake into the engine. After entering the intake manifold, the air mixes with gasoline to form a combustible mixture, which then ignites to generate power. Positioned between the air filter and the engine block, it is often referred to as the throat of the automobile engine.

How to Prevent Theft of External Tire Pressure Monitoring Sensors?

External sensors have relatively weaker anti-theft properties, but there are now anti-theft nuts available that require specialized wrenches for installation and removal. Specific details are as follows: 1. Disadvantages of external types: External Tire Pressure Monitoring Systems (TPMS) with sensors outside the valve stem are more vulnerable. They cannot accurately assess the internal conditions of the tire and have not undergone factory testing. The externally mounted sensors on the valve stem can be easily damaged by human or physical interference. Sensors attached externally to the valve stem are even more hazardous. Since they can only detect the tire pressure and temperature inside the valve stem, a Tire-Review feature report in the U.S. referred to them as 'adult toys.' Additionally, they are susceptible to damage from human or physical interference at any time. 2. Principle of external types: External tire pressure monitoring sensors are screwed onto the valve stem to monitor tire pressure by blocking the valve pin. Moreover, if the owner's tires have not been dynamically balanced, prolonged use can lead to air leakage. Driving for extended periods with unbalanced tires results in increased tire wear, higher fuel consumption, and greater damage to the vehicle, making their use potentially dangerous.

How to Book Training for Subject 2?

Book an appointment on the official website of the local vehicle management office. Below is more information about Subject 2: 1. Test Content: Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment. It refers to the field driving skills test. For small vehicles (C1/C2), the test items include five mandatory components: reversing into a garage, parallel parking, stopping and starting on a slope, turning at a right angle, and curve driving (commonly known as the S-curve). Some regions may include a sixth item: high-speed toll card collection. 2. Passing Criteria: The full score is 100 points, with evaluation standards set for failing, deducting 20 points, deducting 10 points, and deducting 5 points.

How to Troubleshoot When the Engine Fault Light Comes On?

When the engine fault light comes on, it indicates the following situations: a yellow symbol light indicates a fault in the engine; a red symbol light indicates a serious fault in the engine. Here is more information about the engine fault light: 1. Elimination method: Simply remove the fuse. 2. Solutions for when the engine fault light comes on: (1) Clean the engine: Once the engine fault light comes on, the owner should promptly clean the carbon deposits in the engine. (2) Improve fuel quality. (3) Use higher-grade gasoline: After cleaning the engine, the owner can choose to use 95 or 97 octane gasoline.

Should You Release the Handbrake or Shift Gears First When Starting an Automatic Car?

When starting an automatic car, you should shift gears first and then release the handbrake. Below is relevant information about automatic transmission vehicles: 1. Working Principle: Automatic transmissions primarily rely on the hydraulic transmission principle of torque converters to complete gear shifts; the vehicle automatically selects the appropriate gear based on driving speed and traffic conditions, making gear shifts safer. 2. Advantages of Automatic Transmissions: Automatic transmissions use a torque converter to replace the clutch in manual transmission cars, so there's no need for frequent gear shifting. In terms of operational convenience, automatic transmissions are more suitable for beginners.

How to Solve Excessive Engine Noise During Acceleration?

Here are the specific causes and solutions for excessive engine noise during acceleration: 1. Dirty throttle valve: When encountering loud engine noise during acceleration, the throttle valve should be considered first. If the throttle valve is dirty, this situation may occur, and cleaning the throttle valve once can be considered. 2. Intake manifold leakage: Unwanted air, gasoline vapor, or exhaust gas entering the intake manifold can cause the air-fuel mixture to be too rich or too lean, leading to loud engine noise during acceleration; consider sending it to a 4S shop for inspection and repair. 3. Abnormal spark plugs: Problems with the ignition coil or spark plugs in the ignition system may also cause such a situation. Check if the spark plugs are clogged, and timely replacement can improve this situation. 4. Damaged oxygen sensor: The oxygen sensor in the intake and exhaust system may sometimes be damaged, causing inaccurate intake data and also resulting in loud engine noise during acceleration, requiring it to be sent to a 4S shop for inspection and repair.
