What causes the car engine yellow light to flash and shake?
2 Answers
The reason for the engine yellow light flashing and shaking is that the engine has malfunctioned. The following are the causes of the engine yellow light flashing and shaking: 1. Poor combustion of the engine's air-fuel mixture. When the mixture in the cylinder is too rich, the vehicle may experience symptoms such as knocking and shaking. 2. Malfunction of spark plugs, high-voltage wires, or ignition coils. 3. Abnormal fuel supply pressure or failure of the intake pressure sensor. Below are the solutions for the 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 operate normally without any additional abnormalities, try restarting the car. 3. If the car shows symptoms such as lack of acceleration or abnormal engine noise after the yellow light comes on, stop immediately and inspect for repairs.
The engine warning light keeps flashing and the car is shaking so badly it's terrifying. As an experienced driver for many years, I've encountered similar situations a few times. Usually, this indicates severe cylinder misfires, causing the engine to shake due to imbalance. The reasons are mostly related to ignition system failures, such as spark plugs aged and clogged by carbon deposits, ignition coils short-circuited and burnt out, or loose wiring connections. It could also be due to a weak fuel pump or clogged fuel injectors leading to insufficient fuel supply. Not to mention faulty sensors like the oxygen sensor sending wrong signals, making the shaking worse. Don't underestimate it—a flashing yellow light indicates an urgent issue. Delaying repairs can lead to catalytic converter damage, costing at least a couple thousand to replace, or even worse, engine seizure, leaving you stranded dangerously on the road. I recommend immediately taking it to a reputable auto repair shop to scan the trouble codes for targeted fixes—don’t just settle for a random roadside stall. Before starting the car, always check the engine oil level to avoid unexpected mishaps.
