What's the reason for engine warning light and car shaking?
2 Answers
The cause is engine malfunction. Here are the reasons for engine problems: 1. Engine misfire: This refers to when one cylinder in a multi-cylinder engine stops working, causing symptoms like abnormal shaking and weak acceleration. Professional inspection and repair are needed. 2. Engine overheating: After prolonged or aggressive driving, engine temperature may exceed normal levels triggering the warning light. Simply park to let it cool naturally. 3. Severe carbon buildup: Excessive carbon deposits can cause weak acceleration and increased fuel consumption, requiring timely cleaning. 4. Poor fuel quality: Low-quality fuel affects engine performance, requiring switching to higher quality fuel.
Oh no, my engine warning light suddenly came on, and the car is shaking badly. I've encountered this issue quite a few times. It's usually caused by faulty spark plugs or ignition coils, leading to misfiring in one of the cylinders. Common reasons include excessive carbon buildup from long-term lack of maintenance or poor fuel quality. You'll notice significant steering wheel vibration, especially at idle. It needs immediate attention—first, use an OBD scanner to read the trouble codes. If it shows ignition system codes, just replace the spark plugs. If it's a fuel system issue, the injectors might be clogged. Definitely don't drive it long distances like this, or the engine could suffer serious damage. Regularly pay attention to oil and air filter changes—preventive maintenance can save you a lot of trouble.
