What Causes Engine Shaking at Low Speeds but Normal Operation at High Speeds?

Engine shaking at low speeds but normal operation at high speeds is mainly due to carbon buildup in the throttle body. Here is an introduction to the throttle body: 1. Introduction: The throttle body is a controllable valve that regulates the amount of air entering the engine. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture, which then burns to generate power. 2. Maintenance Methods: (1) Release of Gases: Engine oil tends to volatilize when heated during use. The longer the usage period and the higher the temperature, the stronger the volatilization. Additionally, some compressed gas from the cylinder will inevitably squeeze into the crankcase through the gaps in the piston rings. Therefore, there must be a passage to release these gases; otherwise, positive pressure will form in the oil pan. (2) Negative Pressure Extraction: The reason the crankcase ventilation tube is connected to the throttle body is partly due to environmental requirements and partly to utilize the intake's negative pressure to extract gases from the crankcase. (3) Cleaning Frequency: How quickly the throttle body gets dirty depends on various factors, including the engine's operating temperature and driving habits.

Can a car's mileage be reset to zero?

Car mileage can be reset to zero. Here are the precautions for resetting: 1. The new car's odometer has one chance to be reset, but only once. 2. When resetting, the total mileage must not exceed 200 kilometers, otherwise it cannot be reset. 3. After exceeding 200 kilometers or after the total mileage has been reset once, there is no second chance. Here is additional information about car mileage: 1. Car mileage refers to the distance the car has traveled. It shows how many kilometers the car has traveled since it left the factory. 2. The odometer in a passenger car includes two roller counters driven by the same flexible shaft, which respectively accumulate the current mileage and the total mileage. 3. Car mileage is also a standard for measuring vehicle depreciation. Many car owners modify the odometer numbers when selling their vehicles to deceive buyers and raise the selling price. For car buyers, the vehicle's current condition, age, brand, performance, and degree of wear are all pricing standards, as well as the most important criteria for judging whether a vehicle is good or bad. 4. In principle, the lower the number on the odometer, the higher the vehicle's price. Therefore, the number on the odometer is not a uniform standard for judging the quality of a vehicle.

What to do if the license plate fixing screw hole is damaged?

DMV replacement or rivet fixing: If the hole for the license plate fixing screw is damaged, you can go to the DMV for a replacement or use rivets to re-fix the license plate. You can also dismantle it, weld a bolt, apply anti-rust coating, or offset the screw hole position and drill a hole in the license plate. Below is relevant information: 1. Replacing screws: If you need to replace screws, go directly to the DMV to apply for them. However, it's important to note that screws in each province, city, and region have special identifiers, and you must not install them randomly. For example, license plate screws in Shenzhen all have the "Yue B" identifier, and vehicles from other regions cannot use them. 2. Requirements: All factory vehicles must be equipped with 4 fixed seals. Within the normal range, vehicles with either 2 or 4 fixed seals are acceptable, and you won't be penalized or fined for having only 2 instead of 4. It is only a violation if the license plate has 4 fixed seal positions but the owner only installs 2 screws. For not installing the vehicle license plate number as required, a one-time deduction of 12 points may be applied.

Does the score reset to twelve points after license renewal?

No, the score does not reset to 12 points immediately after license renewal. Instead, at the end of a scoring cycle, if all traffic violations have been processed, the system will automatically clear the points and start anew. Below are the relevant legal provisions: 1. Article 65: The cumulative scoring cycle for road traffic safety violations (i.e., the scoring cycle) is 12 months, with a maximum of 12 points, calculated from the date the motor vehicle driver's license is first issued. Depending on the severity of the road traffic safety violation, the points deducted in a single instance can be one of five levels: 12 points, 6 points, 3 points, 2 points, or 1 point. 2. Article 68: If a motor vehicle driver accumulates 12 points within a scoring cycle, the traffic management department of the public security organ shall detain their motor vehicle driver's license. If a motor vehicle driver accumulates 12 points or more twice within a scoring cycle or accumulates 24 points or more, the vehicle management office shall also conduct a road driving skills test within ten days after the driver passes the examination on road traffic safety laws, regulations, and related knowledge. For those taking the road driving skills test, the test shall be conducted according to the highest permissible vehicle type specified on their motor vehicle driver's license.

Is the 2009 Buick Excelle Fuel-Efficient?

Is the 2009 Buick Excelle fuel-efficient? Below are the methods to reduce fuel consumption and factors affecting it: Methods to reduce fuel consumption: You can add fuel additives to the fuel tank to improve combustion and remove carbon deposits. It is recommended to regularly inspect and maintain the vehicle, clean or replace the three filters, which will help reduce fuel consumption. Additionally, the longer the vehicle idles, the more fuel it consumes, so try to minimize idle time. Avoid rapid acceleration, slamming the gas pedal, and driving at low RPMs. Factors affecting fuel consumption: Various driving conditions such as acceleration, deceleration, braking, and engine idling, as well as load capacity, temperature, and whether the air conditioning is on, can all impact the vehicle's fuel consumption.
