How much over the speed limit is driving at 79 in a 70 zone?

What Causes Unstable Idle Speed Fluctuations During Cold Start?

Unstable idle speed fluctuations during cold start are primarily caused by excessive carbon buildup in the throttle body and intake passages. Below are the relevant explanations: 1. Intake manifold or valve leaks: Incorrect engine air intake can result in overly rich or lean air-fuel mixture, leading to abnormal combustion. This causes engine idle fluctuations. When leaks affect engine vacuum, severe vibrations occur, particularly impacting cold idle. Common causes include aged intake manifold gaskets causing leaks or damaged intake manifolds. 2. Excessive carbon deposits in throttle body and intake passages: Carbon buildup and dirt accumulation in the throttle body and surrounding intake passages alter the air channel cross-sectional area, preventing the control unit from precisely regulating idle air intake. This results in improper combustion due to overly rich or lean mixtures. Common causes include throttle body carbon deposits and oil contamination/carbon buildup in surrounding intake passages.

Do I need to collect the inspection sticker during the biennial vehicle inspection?

During the biennial vehicle inspection, you do need to collect the inspection sticker. Here are the specific details: 1. Exemption: New vehicles enjoy a 6-year exemption from physical inspection, but the annual inspection sticker must be renewed every two years. The exemption only means the vehicle doesn't need to go to an inspection station. Nowadays, you can obtain the biennial inspection sticker without leaving your home, simply by using your smartphone. 2. Vehicle inspection notes: Please note that for small and micro non-commercial passenger vehicles, within 6 years, inspection is required every 2 years; after 6 years, annual inspection is required; after 15 years, inspection is required twice a year. For commercial passenger vehicles, within 5 years, annual inspection is required; after 5 years, inspection is required every 6 months. For trucks and large/medium-sized non-commercial passenger vehicles, within 10 years, annual inspection is required; after 10 years, inspection is required every 6 months.

Can a New Car Go Directly on the Highway?

A new car can go directly on the highway. Here are the specific details: 1. Try to avoid emergency braking: Emergency braking not only impacts the braking system during the break-in period but also increases the load on the chassis and engine. It is best to avoid emergency braking within the first 300 kilometers of driving. 2. Avoid overloading: If a new car is fully loaded during the break-in period, it can cause damage to the components. Therefore, within the first 1,000 kilometers, the load should generally not exceed 75%-80% of the rated capacity. 3. Driving on the highway: During the break-in period, driving long distances on the highway increases the continuous working time of the engine, which can lead to component wear. It is recommended to maintain a speed of 120 km/h with the engine speed not exceeding 3,000 RPM. If the speed exceeds 3,000 RPM, consider reducing the speed to keep it at 3,000 RPM. During long-distance driving, take a break of about ten minutes at service areas.

How to Solve the Problem of Skoda Octavia Brake Light Staying On?

Skoda Octavia brake light staying on solutions: 1. If the brake light stays on, brake fluid should be added. 2. It could be that the tail light bulb is damaged, and replacing the bulb will solve the problem. 3. If the brake pads are severely worn, the light may also stay on, and the brake pads need to be replaced. Below is relevant information about the brake light: 1. Lack of brake fluid, which is an essential part of the car's braking system. When the driver steps on the brake pedal, the force applied is transmitted by the piston in the master cylinder through the brake fluid to the wheel cylinders at each wheel, causing the brake pads to contact the wheels and stop the vehicle. 2. Tail light bulb damage. The brake fluid reservoir has upper and lower lines. When the brake fluid level falls below the lower line, the sensor next to the reservoir detects this and reflects it on the dashboard. If the brake fluid decreases rapidly, it indicates a leak in the braking system.

What Causes the Oil Pump to Fail?

The following are the reasons for oil pump damage: 1. Wear between the plunger and plunger sleeve: During operation, mechanical impurities in the fuel enter the injection pump chamber, causing abrasive wear. Combined with the corrosive effect of the fuel, this increases the gap between the plunger and sleeve. 2. Wear of the delivery valve: High-speed flow scouring by mechanical impurities in the fuel causes wear on the delivery valve, pressure relief band, or valve seat, leading to poor sealing and insufficient residual pressure in the high-pressure fuel line. Additional information on the causes of damage: 1. Failure of the delivery valve spring: Fatigue reduces the spring force of the delivery valve, impairing its one-way shut-off function and causing backflow. 2. Insufficient pressure in the low-pressure fuel line: Reduced or no pumping capability of the fuel supply pump, clogged diesel filters or fuel lines, or air entering the fuel system can decrease the fuel pressure in the low-pressure line of the injection pump, preventing pressure generation. When the injection pump operates, fuel cannot quickly enter the pump chamber, resulting in no or insufficient fuel injection.
