5.4 Slight whine at idle
I have an 2007 F150 5.4 and have noticed a slight whine when it idles. I changed the serpentine belt about a month ago (which helped, but it's still there). It doesn't get louder when I accelerate, and it doesn't sound like the transmission, but I'm totally lost on what it could be. Thoughts/ideas?
