I assume that by "engine vibration" you mean idle. There is nearly a million and one things that can cause a rough idle. What year car or engine do you have? When does it vibrate abnormally (ex.: when sitting at a red light or when revving)? Have you done anything to the car recently? Is your check engine light on?
