What Causes Engine Misfire and Vibration?

[VonAiden]

Engine vibration issues are likely caused by the following factors: 1. Poor combustion state; 2. Engine knocking; 3. Low-quality fuel; 4. Dirty engine cylinders with carbon deposits, etc. More relevant information is as follows: 1. If you notice slight trembling of the engine after starting the vehicle and opening the hood, this kind of steady, rhythmic vibration is normal. However, if you detect obvious engine shaking while driving, it's advisable to visit a 4S shop for inspection. 2. If your vehicle's warning light comes on, especially if accompanied by high coolant temperature or low oil pressure warnings, and you can clearly sense the malfunction, it's recommended to stop immediately and call for a tow truck or roadside assistance. The engine warning light indicates current system faults requiring prompt inspection and repair. The vehicle's ECU will store this fault information for mechanics' reference during maintenance, enabling quicker troubleshooting. Finally, to allow continued engine operation despite faults, the system will clear error codes if detected issues don't significantly affect engine performance.
