What Causes the Engine Yellow Light to Flash and Shake?
2 Answers
The reasons for the engine yellow light flashing and shaking are: 1. Poor combustion of the engine's air-fuel mixture, resulting in an overly rich mixture in the cylinders; 2. Faulty spark plugs, high-voltage wires, or ignition coils; 3. Abnormal fuel supply pressure or a malfunctioning intake pressure sensor. Solutions for engine yellow light flashing and shaking: 1. If the car cannot start, it needs to be towed to a nearby repair shop for inspection and repair; 2. If the car can drive normally without any additional abnormalities, try restarting the car; 3. If the car exhibits symptoms such as loss of power during acceleration or abnormal engine noises after the yellow light comes on, stop immediately and inspect for repairs.
When I first started driving, I encountered the engine yellow light flashing and shaking, which really freaked me out. I asked the repair shop, and they said it was an engine misfire, possibly due to burnt spark plugs or faulty ignition coils. The shaking was caused by uneven engine ignition, like a person struggling to breathe. If not repaired in time, it could damage the catalytic converter, leading to higher repair costs. My car was old at the time, and replacing the spark plugs fixed the issue later. Regularly checking these parts during maintenance can save a lot of trouble. Remember, a flashing yellow light indicates a serious problem—don’t force driving on the highway; pulling over is safer. Don’t attempt DIY repairs; leave it to the professionals for a reliable fix.
