What to Do When the Engine Warning Light Is On and the Car Shakes?

If the engine warning light is on and the car shakes, you should call the 4S shop or a professional auto repair shop for help, request a tow truck, or wait for rescue. Do not risk continuing to drive. Reasons for the engine warning light being on and the car shaking: 1. The ignition system has malfunctioned, and the working conditions of the spark plugs, high-voltage wires, and ignition coils are faulty, leading to poor ignition system performance; 2. The mixture in the cylinder is too rich, causing symptoms such as knocking and shaking in the vehicle. An engine (Engine) is a machine capable of converting other forms of energy into mechanical energy. It was invented in the UK and can refer to either the power generation device or the entire machine, including the power unit.
Last time I was driving my old Accord on the highway, I encountered the same situation. The engine light suddenly came on, and the car was shaking like a massage chair. I immediately slowed down and pulled over, turned on the hazard lights, and checked the oil dipstick and coolant—fortunately, the levels were normal. My first thought was a misfire, most likely an issue with the ignition system, since spark plugs typically last only about 70,000 to 80,000 kilometers. I remember the mechanic taught me that in such cases, it's best not to push through—just find a nearby repair shop to read the trouble codes. Otherwise, if the ignition coil burns out, it'd be even more troublesome. In the end, replacing a set of spark plugs fixed the issue. Spending a few hundred bucks is much better than a major repair. Safety on the road is the top priority—never take risks with a shaking car.
I know a thing or two about cars. When the engine light comes on along with shaking, it's definitely not a minor issue. Common causes include a faulty ignition coil leading to a misfire, clogged fuel injectors due to carbon buildup, or unstable fuel pressure. First, check the condition of the engine oil and oil filter—if there's a lot of sludge, change them immediately. If you can't figure it out yourself, remember to take it to a shop and use a diagnostic tool to read the trouble codes—it can save a lot of guesswork. Especially don't overlook those small sensors; a dirty oxygen sensor can also cause shaking. My neighbor's Civic was fixed that way before.
