I'm pretty sure something has fallen out of my engine bay whilst driving. For a couple of weeks i have heard a vibration (or at least i hope it was and not a grinding noise) coming from the engine bay when i get to around 2k+ revs. Driving along today i was distracted by the other half and thought i hit something in the road however she says it felt and sounded like it came of the rear of the car. Magically the grinding / vibration has stopped. I'm glad it has stopped but worried to what could have potentially fallen off the car! Don't suppose anyone has had anything similar happen or may have any ideas as to what it could be? I appreciate it's a bit of a tricky one just curious (and worried) to anyone elses experience.
