Encountering a Buick Excelle reporting Code 68 fault? I've fixed many similar cases! Code 68 often indicates a throttle position sensor issue or other sensor malfunctions. Don't panic—first use a diagnostic tool to read the exact code. If it's just a dirty throttle or loose wiring, you can try DIY steps: disconnect the battery negative terminal for 10 minutes then reconnect to reset the ECU. However, most cases require professional inspection, such as checking the intake manifold, mass airflow sensor, or vacuum lines for leaks. Safety first—engine power may fluctuate while driving, so head to a repair shop promptly. Avoid cheap roadside stalls; Buick-authorized service centers better understand factory-specific issues. Preventive measures include regular engine bay maintenance and cleaning sensor areas.

What to Bring for a Car's First Maintenance?

Items required for the first maintenance include: driver's license; maintenance manual; warranty manual; owner's ID card; vehicle's registration certificate; vehicle's purchase invoice, to be taken to the designated first maintenance facility for the vehicle's initial service. Important note: Make an appointment with the 4S store in advance. The first maintenance refers to the initial service after a new car has been driven, with the specific timing varying by vehicle, typically after driving 1,000 to 3,000 kilometers. It's crucial to attend the first maintenance promptly, neither too early nor too late. The completion of the first maintenance signifies the end of the car's break-in period, allowing the vehicle to be driven under standard load and normal speed as required. The timing for the first maintenance is calculated from the date of vehicle pickup. There are two indicator values for the first maintenance timing: mileage and time. Whichever comes first serves as the standard. First maintenance tasks include: changing the engine oil and oil filter, cleaning the air filter, checking various fluid levels for normalcy, inspecting the generator belt and wiper blades for damage, checking tire pressure for normalcy, and examining tires for damage or bulges. Estimated time required: Approximately 2 hours to complete all tasks. The most critical aspect of a new car's first maintenance is changing the engine oil and oil filter. When changing the oil, the oil filter must also be replaced simultaneously. The selection of engine oil must refer to the "Vehicle Usage and Maintenance Manual," as different vehicle models specify different oil grades. Maintenance precautions: Do not rinse the interior of the car body with water: Many people clean their cars during holidays, washing the body with water and wiping it with a cloth. It's important to note that the interior of the car body should not be directly washed with water. If the floor mats are dirty, they can be cleaned with a vacuum cleaner or removed, scrubbed with a brush and detergent, dried, and then placed back. There are many drainage holes under the rubber mats on the floor of the driver's compartment. If water enters, it won't dry naturally but will flow through these holes to areas like the transmission, causing erosion and corrosion. The best practice is to clean with a vacuum cleaner and then wipe with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: When the car's antifreeze is low, it's recommended to drain the antifreeze and add the same brand from the start. Since antifreeze brands differ, their chemical properties vary significantly. Various functional additives can corrode those from other brands. Different brands of antifreeze use different additives, so they should not be mixed to avoid unnecessary issues. Do not lubricate tire bolts and nuts: When bolts on a moving car rust, they are often oiled to function properly again. Some people apply lubricant to the bolts and nuts to prevent rust, but this introduces unnecessary risks to safe driving. At high speeds, bolts and nuts can easily loosen or even fall out, leading to driving failures. Do not press the accelerator when starting an EFI car: The starter of an EFI (Electronic Fuel Injection) car differs from that of a conventional car. Its fuel injection control device can automatically adjust the fuel supply based on the starter's temperature and operating conditions, ensuring a smooth start.

What is the standard tire pressure?

Standard tire pressure ranges between 2.3 and 2.5 bar. Tire pressure refers to the air pressure inside the tire, and the level of tire pressure plays a crucial role in a vehicle's performance and power. Tires are rolling objects installed on various vehicles or machinery that come into contact with the ground. Tires are often used under complex and demanding conditions, enduring various deformations, loads, forces, and high and low temperatures during operation. Therefore, they must have high load-bearing capacity, traction performance, and cushioning performance. Tires can be categorized by their intended use into: passenger car tires, light truck tires, construction machinery tires, off-road vehicle tires, agricultural and forestry machinery tires, industrial vehicle tires, motorcycle tires, aviation tires, and special vehicle tires.
