Скачать или смотреть Why Did My Car Suddenly Stall While Driving?

A vehicle stalling while driving can stem from critical failures across multiple systems: fuel delivery (e.g., clogged filters, failing pumps or regulators), ignition (bad coils, spark plugs, crank/cam sensors), air intake or vacuum (faulty MAF/MAP, leaks, throttle/IAC issues), sensor/ECM inputs (TPS, O₂, coolant‐temp), electrical/charging (weak alternator/battery, poor grounds, blown fuses) or mechanical load (seized accessories, transmission drag, belt failure). Common symptoms include sudden shut‑off—sometimes under load or at highway speed—with erratic running or flickering electronics before stalls. Diagnosis follows a methodical path: scan for codes and log live data, check voltage under load, measure fuel pressure, inspect ignition components and timing signals, clean sensors and smoke‑test intake, validate sensor outputs, test wiring and grounds, and examine accessory loads, followed by a road test. Urgency is highest for ignition and fuel failures, followed by electrical issues; sensor, intake and accessory faults are medium‑level concerns. Stalling incidents should prompt offline diagnostics using data logs and oscilloscopy before replacing parts. Preventively, maintain fuel filters, spark/coils, intake systems, battery/grounds, sensors, and belts per OEM intervals. Provide your vehicle’s make/model, odometer, codes, and live data to refine the diagnosis.
