Hey Guys, I noticed that when I am picking up speed, my v6 engine vibrates more violently than it does while cruising. My assumption is the vibration is present given the fact that I am accelerating from zero initial velocity. just to paint a picture it vibrates rather much below 30mph, then anywhere pass this, the engine rocks significantly in a sudden, causing a moderate jerk. Am I right in what I have assumed, or is there a problem?
