i have the same issue... i have a bit of vibration throughout the whole car when standing still... Hope someone has an answerHow do I know when my engine mounts could do with replacing? I notice that if the car is still, brake on, and in neutral, a sharp blip of the throttle causes the whole car to vibrate in sympathy! It's hard to explain - the chassis moves noticeably. I know the engine is powerful, but should this happen? I was wondering if my engine mounts are not insulating the chassis from the engine as they should?
