What causes a Baojun 730 to suddenly stall during normal driving?

It may be caused by excessive carbon buildup in areas such as the throttle body, idle speed motor, intake valves, intake pipes, combustion chamber, spark plugs, and fuel injectors. Below is relevant information: 1. Overview: Baojun is an independent automotive brand established by SAIC-GM-Wuling in 2010. The name 'Baojun' originates from the meaning of 'fine steed,' symbolizing people's most beloved horse. Baojun vehicles fully integrate the superior resources of SAIC, GM, and Wuling. 2. Models: Since its inception, Baojun has successively launched family sedans like the Baojun 630 and Baojun 610, SUV models such as the Baojun 510 and Baojun 530, MPV models including the Baojun 730 and Baojun 360, compact cars like the Baojun 310 and Baojun 310W, as well as new energy electric vehicles such as the Baojun E100 and Baojun E200.

I once encountered a situation where the Baojun 730 suddenly stalled while driving, which could be related to several common faults. The most common issue is fuel supply problems, such as a malfunctioning fuel pump failing to deliver gasoline to the engine, or a clogged fuel filter causing poor fuel delivery. If the fuel gauge shows normal levels but the car still stalls, it might be due to severely worn spark plugs unable to ignite properly or an aging ignition coil causing system failure. Additionally, poor contact in the high-voltage wiring can also lead to sudden power loss. Stalling while driving is particularly dangerous, so I recommend immediately turning on the hazard lights and pulling over slowly to avoid secondary accidents. Remember to check if the engine warning light is on, and it's best to visit a professional repair shop as soon as possible to diagnose the specific cause. Avoid attempting DIY repairs to prevent worsening the problem. Regular maintenance, including cleaning the fuel system and inspecting the ignition system, can effectively prevent such sudden failures.

My Baojun 730 had similar issues before - it would suddenly stall while driving. Usually the electrical system is the key focus. Insufficient battery power is one of the main causes, where sudden voltage drops can trigger automatic system shutdown, especially when activating AC or high-load devices. Another possibility is alternator failure not charging the battery, leading to power depletion. Check if the fan belt is loose or if the alternator is malfunctioning. Don't overlook sensor issues either - for example, a faulty crankshaft position sensor sending wrong signals could make the engine computer misinterpret it as a parking state. With safety first, don't rush to restart after stopping. Use your phone to record fault details to help mechanics diagnose. Regular maintenance like cleaning battery terminals can reduce risks.

The sudden stalling of the Baojun 730 may be caused by fuel or ignition system failures. If the fuel pump fails and interrupts the fuel supply, the engine will stall, or if the spark plugs are worn out and cannot ignite the air-fuel mixture. Additionally, a clogged air filter can affect air intake and cause the engine to stop working. Issues with control modules such as the ECU are also common, and improper handling can lead to unexplained stalling. The safe way to handle this is to turn off electrical devices, release the brake, and park the car for inspection. During maintenance, pay attention to replacing vulnerable parts to avoid potential hazards.
