Golly I hope I am over-reacting and being paranoid, but in my experience with vehicles, I rarely am...
Bronco hit 1800 miles recently and suddenly its making an odd fluttering sound when accelerating - seems to be correlated to the RPM's.
It borderline sounds like a leaf is stuck in a fan blade - however I checked and I see no leaves or other debris anywhere in the engine bay.
Video of the sound below - it becomes very prominent at about 12 seconds into the video. make sure your speakers are cranked as its hard to record from inside the cabin.
Does anyone's Bronco sound like this while under acceleration? Any idea what this could be?
Another note; I've noticed when I initially start the truck she idles at 1.2k RPM - is that standard?
