How to Determine if Engine Vibration is Normal?

[DeEllie]

"Under normal circumstances, car engine vibration should be very smooth and regular. If you can clearly feel that the engine vibration has increased recently, then a fault inspection is required. When the motor vehicle is idling, if the vehicle's accelerator pedal, brake pedal, steering wheel, or gear lever shows vibration, it can be determined as abnormal engine vibration. At this time, it is necessary to check whether the engine has a misfire or incomplete combustion and carry out repairs. If the car engine vibrates more severely than usual while driving, and sometimes there is even a problem with starting the engine, it may be due to a dirty throttle, excessive carbon deposits in the fuel injector or intake tract. In cold conditions, carbon deposits can absorb some fuel, and if the fuel does not completely enter the cylinder for combustion, it can cause unstable idling and difficulty starting."
