What are the reasons for the Changan Eado stalling while driving?

It could be caused by poor fuel flow in the vehicle, faults in components such as the fuel injector and spark plug. Below is relevant information: 1. Carbon deposits: Carbon deposits include cylinder carbon deposits, throttle carbon deposits, spark plug carbon deposits, and intake carbon deposits. These areas are closely related to the engine's power output. When there is excessive carbon buildup inside the engine, the vehicle's ignition energy decreases, intake efficiency drops, ultimately leading to reduced engine power, resulting in sluggish acceleration and a muffled sound. 2. Fuel system: Adding incompatible fuel octane ratings can cause a decrease in the vehicle's output power and reduced performance. Alternatively, if the fuel tank cap vent is blocked, or if the fuel tank switch, fuel filter, or the fuel line between the fuel tank and the carburetor are partially clogged, it may not meet the required fuel supply, leading to a lean air-fuel mixture and weak engine acceleration.
I used to drive a Changan Eado and often encountered sudden engine stalls while driving. The main reasons could be fuel system issues, such as a faulty fuel pump or clogged fuel filter. Insufficient fuel supply causes the engine to stop, especially during acceleration. Another common cause is excessive carbon buildup, where dirty fuel injectors lead to uneven fuel distribution. I've experienced this myself – a sudden stall on the highway is extremely dangerous, requiring immediate pulling over for inspection. Regular maintenance of the fuel system is crucial: clean the fuel tank periodically, replace filters before problems arise. A severely dirty air filter can also affect the air-fuel mixture, potentially causing engine stalls. Ultimately, these issues relate to daily driving habits – always pay attention to changes in engine sound while driving.
From an electrical perspective, frequent stalling in the Changan Eado is often related to circuit malfunctions, including insufficient battery charge or an aging alternator, which can cause the engine to stop due to power interruption. Burned-out relays or fuses may also trigger stalling, as the vehicle's control system requires stable voltage to operate. I once tested with a voltmeter and found that fluctuating voltage was the issue. Additionally, aging ignition coils or spark plugs can cause ignition failure, leading to sudden stalling. If the Electronic Control Unit (ECU) has bugs, it can also result in the same problem, though restarting the car sometimes resolves it. It's advisable to regularly check the battery's lifespan, as electronic components are more prone to failure during high summer temperatures—ensure proper ventilation and cooling. If the car stalls, don't panic; first, shift to neutral and try restarting.
I've encountered the issue of the Eado stalling several times, mainly due to faulty sensors or small components. For instance, a malfunctioning throttle position sensor can send erroneous signals causing the engine to stop. Another major reason is air entering the fuel line, leading to poor fuel supply. When driving this car, I noticed unstable idling was a precursor, which was later resolved by a mechanic who checked the fuel pump. Safety-wise, be aware that the steering wheel may become heavy after stalling, so slowly pull over to the side for inspection and repair.
