What does it mean when the engine malfunction indicator light is flashing?

[DiRachel]

Reasons for the engine malfunction indicator light flashing: 1. Poor quality gasoline that does not meet standards, causing the engine malfunction light to illuminate; 2. Damaged or loose oxygen sensor or sensor connector, leading to a mixture that is too lean or too rich, which can trigger the malfunction light; 3. A malfunctioning air flow sensor may not prevent the engine from starting, but issues such as unstable idling, poor acceleration, backfiring in the intake manifold, and black smoke from the exhaust pipe are highly possible. The vehicle malfunction light is often caused by the fuel emission system. When the malfunction light is on, start and turn off the vehicle three times, then start it again to observe if the malfunction light remains illuminated. If it does, promptly visit a repair shop to check the fault codes.
