Too much vacuum???
2005 f150 5.4l 3v
hello all,
my truck squeaks (chirps) from idle to 1500 rpm. It finally went away when my small breather tube chaffed and wore through. Once I replaced the tube the chirp was back. I have noticed when I take my oil cap off, I put my hand over it an it sucks my hand down pretty hard. I removed my pcv tube on the driver side and my truck won't even hold idle. What can cause this major vacuum?
