What Causes the Engine Warning Light to Flash and Severe Vibration?
2 Answers
Engine warning light flashing and severe vibration are caused by: 1. The engine intake may have sucked in a small amount of water, requiring inspection of the air filter; 2. During water wading, excessive exhaust resistance leads to poor exhaust, causing a temporary phenomenon of excessive fuel and insufficient air, resulting in incomplete combustion of gasoline. Solutions for engine warning light flashing and severe vibration: 1. Check the water temperature gauge and oil pressure warning light; 2. If the water temperature is too high or the oil pressure warning light is on, and you can clearly feel that the vehicle has a malfunction, you should immediately pull over, call for assistance, and avoid affecting the engine's performance.
I've been driving for decades, and when I see the engine warning light flashing while the car shakes violently, it usually indicates a major issue with the ignition or fuel system. Worn-out or burnt spark plugs, faulty ignition coils causing unstable current, leading to cylinders misfiring; insufficient fuel pump pressure or clogged fuel injectors resulting in uneven air-fuel mixture; malfunctioning oxygen sensors or crankshaft position sensors causing ECU control chaos. This severe shaking is a sign of engine misfire. If you keep driving forcefully, unburned fuel may flow into the exhaust pipe and damage the catalytic converter, doubling repair costs. Safety first—find a place to pull over and turn off the engine immediately. Don't delay. Regular maintenance like replacing spark plugs and fuel filters is recommended to prevent such troubles.
