So as a nice xmas gift, my truck decided to have a new problem. All of a sudden the truck started whistling during acceleration. At first it just happened when taking off from a stop. Then it started doing it when I was accelerating at abt 45 mph. Any idea what this could be??
Btw- 2001 f350 v-10

 

A whistle perhaps?

Kind of hard to troubleshoot a noise over the internet without taking a video of it and put it on youtube.
