Generally, sudden stalling while driving is caused by an empty fuel tank, electrical issues, ignition coil failure, or fuel pump damage. Here is some relevant information: 1. There are many reasons why a car may stall. If the stalling is not very sudden and the car first feels like it is struggling to get fuel, with the situation worsening until it stalls, this is mostly due to a fuel system issue. If the stalling is very sudden, it is often an electrical problem, such as a burnt-out ignition coil, a blown fuse, or damage or disconnection of key sensors. A specific diagnosis can only be obtained by taking the car to a 4S shop for inspection. 2. After discovering the stall, depending on the road conditions at the time, if there is no emergency, you can slowly apply the brakes to prevent rear-end collisions. After the speed decreases, gently steer the vehicle toward the roadside lane. Note that the brakes should be applied continuously, with increasing pressure—do not release and reapply them, as this will deplete the remaining vacuum, making it impossible to brake again.

Is Idling Harmful to Cars?

Idling is harmful to cars, and the hazards include: 1. Increased engine carbon deposits; 2. Shortened engine lifespan; 3. Overly rich air-fuel mixture in the engine, which can easily damage the three-way catalytic converter; 4. Loosening of the vehicle's braking system, increasing the risk of accidents; 5. Increased exhaust emissions from the vehicle's cylinders. Car idling refers to an operating condition where the engine runs without load, only overcoming internal friction resistance without outputting power, maintaining the minimum stable engine speed. The idle speed can be adjusted by modifying the throttle opening and idle fuel supply.

What is the 909018 tire interchangeable with?

909018 tires cannot be interchanged with other tires. This is because different tire brands have different tread patterns, and their performance characteristics will certainly vary. During acceleration and braking, it is the tire's grip that matters. Take acceleration for example: if the two front tires are different, with one having strong grip and the other weak, during hard acceleration, the tire with weak grip will spin in place while the one with strong grip will propel forward, inevitably causing the vehicle to pull toward the side with weaker grip. Additional Information: 1. Precautions: Under normal driving conditions, front tires generally wear out faster than rear tires. If tire rotation has never been performed, you might replace front tires twice before replacing rear tires once. To extend tire life, regular rotation is necessary, typically every 20,000 kilometers. This ensures even wear across all four tires, allowing them to have nearly identical lifespans so that all four can be replaced simultaneously. 2. Replacement Criteria: Generally, when a tire's remaining life reaches one-third or less of its total lifespan, it should be replaced. For tires that have been driven 70,000 to 80,000 kilometers or more, or are approaching four years or older, their remaining life is usually limited. Consider the age first: regardless of usage, a new tire should be considered for replacement after five years. The mileage at which a tire wears to its limit varies by brand and driving conditions, but it typically falls between 100,000 to 150,000 kilometers.
