What are the reasons why the BYD F3 sometimes stalls automatically?

The following are the reasons why the BYD F3 sometimes stalls automatically: 1. Vacuum leakage in the intake pipe; 2. Unstable idle speed caused by improper idle adjustment, dirty throttle body, poor working condition of the idle speed control system, etc.; 3. Unstable fuel pressure, such as excessive wear or poor contact of the electric fuel pump brush, or clogged fuel pump filter screen, etc.; 4. Poor working condition of the ignition system. Such as weak high-voltage spark, spark plugs used for too long, incorrect ignition timing, poor contact of the ignition coil or inter-turn short circuit in the hot state leading to no high-voltage spark or weak high-voltage spark, poor contact of the low-voltage circuit, damaged insulation adhesive intermittently grounding, poor grounding.
I find the reasons for the BYD F3 sometimes stalling automatically to be quite complex. It could be related to the fuel system, such as the fuel pump not working or the filter being clogged, leading to insufficient fuel supply. It might also be due to a malfunctioning ignition system, with spark plugs fouled or the ignition coil failing, causing ignition failure. If sensors like the crankshaft position sensor fail, the ECU might mistakenly think the engine has stopped and shut it down automatically. Issues such as aging wiring, low battery voltage, or excessive carbon buildup in the throttle body could also lead to this problem. It's recommended to visit a professional repair shop as soon as possible for a check-up, using a diagnostic tool to read fault codes and pinpoint the root cause, to avoid sudden stalling while driving, which could cause accidents. Regular maintenance, including periodic replacement of air filters and spark plugs, can help prevent this hassle.
As a veteran BYD F3 owner with five years of driving experience, I've encountered this issue too. If the car stalls at low speeds or when parked, there's an 80% chance the idle control valve is stuck or dirty - cleaning it usually helps significantly. Excessive carbon buildup in the throttle body affects air intake, causing instant air shortage and stalling. Poor fuel quality is another culprit; always refuel at reputable gas stations. ECU malfunctions or aging batteries are also common causes - the system forces shutdown when power is insufficient. Don't delay repairs; get your wiring and sensors checked ASAP. Safety first! I once procrastinated and nearly rear-ended someone. After repairs, I drove with much greater peace of mind.
