What are the reasons for the Lavida stalling automatically?
2 Answers
Automatic transmission models do not stall easily, while manual transmission models may stall frequently due to poor driving skills. However, it is not impossible for automatic transmission cars to stall. The main reason is the use of low-quality fuel, which causes engine carbon buildup and leads to stalling. Introduction to stalling: Stalling, also known as flameout, occurs when the reactor is operating at a significant reaction rate. If the temperature at the feed inlet is reduced to the lower limit of the multiple steady-state region, the reaction rate suddenly drops significantly, and the reaction basically stops. Precautions: It is best to refuel at reputable, larger gas stations with higher-grade gasoline. Although the price may be higher, the quality of the gasoline is better.
My Lavida suddenly stalled while driving on the highway. After inspection, it turned out to be an issue with the ignition system—the spark plugs were severely carbon-fouled, causing poor ignition. My friend's car had a similar issue due to a faulty fuel pump, as insufficient fuel pressure caused the engine to stop. Malfunctioning sensors like the throttle position sensor can also lead to unstable idling and automatic stalling. I suggest first reading the trouble codes to pinpoint the problem. Regular carbon cleaning can prevent this—don’t ignore minor symptoms, as stalling on the highway is very dangerous. Aging electrical connections can also cause power loss. Replacing spark plugs yourself costs just a few dozen yuan, but repairing the fuel pump requires a professional shop and can cost over a thousand yuan to ensure safety.
