Buick Excelle's jerking during acceleration is generally caused by ignition coil failure and spark plug failure, especially when the jerking gradually disappears after the engine warms up and accelerates, which is referred to as initial acceleration jerking. Additional information: 1. Exterior: The new car adopts Buick's next-generation family design language, with the iconic winged front grille naturally included. The chrome trim on the outer edge of the front grille extends into the headlights, creating an integrated aesthetic. The new headlight design is also more refined. 2. Dimensions: The new car measures 4539/1798/1475mm in length, width, and height, with a wheelbase of 2640mm. 3. Interior: A new brown interior similar to the all-new Regal has been added, with extensive use of leather to enhance the interior quality.

How to Remove and Install a Car Windshield Washer Nozzle?

Methods for removing and installing a car windshield washer nozzle: 1. Locate the nozzle position, then gently pry it up using a screwdriver. The nozzle features a snap-fit design and requires minimal force; 2. Once the nozzle is pried up, you'll see a small connected hose. Simply detach the nozzle from the hose, being careful not to let the hose fall into the car, as this would necessitate removing the entire panel to retrieve it; 3. Install the newly purchased nozzle by carefully placing it into the mounting hole and pressing it downward until it clicks into place; 4. After installation, test the nozzle by spraying water to check the water stream's position on the windshield. If the stream is misaligned, use a needle to adjust the spray direction by inserting it into the nozzle hole until the desired position is achieved.

Can the steering wheel not be moved during straight-line driving in Subject 3?

During straight-line driving in Subject 3, the steering wheel can be adjusted. As long as the vehicle is moving, directional changes will inevitably occur, requiring the student to make slight adjustments to the steering wheel. Below are key points about adjusting the steering wheel: 1. Lightly hold the steering wheel with both hands. Students often get nervous during the Subject 3 test, gripping the steering wheel tightly out of fear that they won't be able to correct any deviation in time. However, holding the steering wheel too tightly actually makes it harder to adjust promptly and may even cause the vehicle to deviate more. Therefore, it's essential to maintain the correct steering wheel posture. 2. Make small adjustments to the steering wheel. Straight-line driving in Subject 3 has specific speed requirements, generally faster, so large steering adjustments can easily be detected by the system as deviations and pose safety risks. Thus, students only need to make small left and right adjustments during straight-line driving. 3. Observe the surroundings. Since the straight-line driving segment in Subject 3 is strict and prohibits significant deviations, 80% of students focus solely on the road ahead to monitor the vehicle's alignment. While keeping the focus ahead is correct during the road test, the exam route also includes other vehicles and pedestrians. To avoid unnecessary collisions, students should also use their peripheral vision to observe reference points and road conditions around them, which increases the chances of success.

What transmission does the Toyota RAV4 use?

Toyota RAV4 uses two types of transmissions: one is a CVT continuously variable transmission, and the other is an ECVT continuously variable transmission. The CVT continuously variable transmission is a type of automatic transmission that does not have actual gears, so there is no shifting hesitation or impact during gear changes, making the entire shifting process very smooth. The Toyota RAV4 has body dimensions of 4600mm in length, 1855mm in width, and 1680mm in height, with a wheelbase of 2690mm. The Toyota RAV4's drivetrain options include front-wheel drive and all-wheel drive, with the all-wheel-drive system being an on-demand type. The front suspension is a MacPherson strut independent suspension, and the rear suspension is an E-type multi-link independent suspension.

What are the consequences of a faulty tensioner pulley?

The consequences of a faulty tensioner pulley: The engine timing will skip teeth, causing ignition and valve timing disorders, engine shaking and difficulty starting. In severe cases, the vehicle may not start at all, and after starting, it may cause the valves to deform. The tensioner pulley is a wear-prone component in automotive parts. Over time, the belt can easily become stretched. Some tensioner pulleys can automatically adjust the belt tension. Additionally, with a tensioner pulley, the belt operates more smoothly, with reduced noise and prevention of slippage. The tensioner pulley is used in the belt tensioning device of the automotive transmission system. It mainly consists of a fixed housing, tensioning arm, pulley body, torsion spring, rolling bearing, and spring bushing, ensuring the transmission system is stable, safe, and reliable.

What maintenance is required for a car that has run 15,000 kilometers?

Maintenance items for a car that has run 15,000 kilometers: 1. Throttle body: Combustion gases in the cylinders may produce some carbon deposits at the throttle body through the intake valves and intake pipes. Over time, these deposits can form dirt, increasing throttle resistance and causing issues like unstable engine idle. 2. Cabin air filter: The cabin air filter contains activated carbon to adsorb fine particles, but the activated carbon diminishes over time and with usage frequency. 3. Tires: If tire rotation hasn't been done by 15,000 kilometers, it's advisable to perform a four-wheel rotation while the tires aren't too worn. Replace the spare tire by taking out one of the current tires and using it as the spare.

What to Do When the Tire Pressure Monitoring Indicator Light Comes On?

Tire pressure monitoring indicator light comes on the processing method: stay calm and do not panic, immediately reduce the speed and avoid fast steering and sudden braking, immediately check the tires, because most cases of tire leakage are caused by nails puncturing the tire resulting in slow air leakage, if normal then drive to the repair shop for inspection, if abnormal then replace the spare tire and go to the repair shop for repair or contact for rescue. There are four reasons why the tire pressure monitoring indicator light stays on: 1. The tire pressure monitoring light comes on due to a punctured tire; 2. Sometimes the tire pressure monitoring light comes on due to excessive tire pressure; 3. The tire pressure monitoring light comes on due to driving with low tire pressure for too long; 4. The tire pressure monitoring light comes on due to prolonged lack of air inflation leading to low tire pressure.
