What Causes the Idle Vibration in Hyundai Elantra?
1 Answers
Modern Hyundai Elantra engine idle vibration may be caused by three main reasons: severe engine carbon deposits, ignition system issues, and unstable oil pressure. Below are the detailed causes of idle vibration in Hyundai Elantra engines: 1. Severe engine carbon deposits: The most common cause of car vibration is a dirty throttle body or excessive carbon deposits on the fuel injectors. 2. Ignition system problems: Check the condition of the spark plugs, high-voltage wires, and ignition coils. Poor ignition system performance or faulty spark plug firing can also lead to such issues. 3. Unstable oil pressure: Abnormal fuel pump pressure or incorrect readings and malfunctioning of the intake pressure sensor can cause vehicle vibration.
