Sonata 8 Idle Vibration Repair Case?
1 Answers
Here are the reasons for the Sonata 8's idle vibration: 1. Dirty throttle body: A dirty or damaged throttle body can cause idle vibration. You can try cleaning the throttle body first. If the issue persists, the throttle body assembly may need to be replaced. 2. Faulty spark plugs: Non-functioning spark plugs can lead to cylinder misfires and idle vibration. Check the spark plugs and ignition module for any faults. 3. Aged or cracked rubber components: The rubber components inside the engine and transmission mounts may have aged or cracked. When these components can no longer absorb the engine's vibrations during operation, idle vibration issues may occur.
