One of the rare times i turn off my radio I hear this thumping noise. Not a knick-knock noise a kinda deep thumping noise. Its under the hood in dash area. I think its a vacuum issue. If I hold down the brakes and turn on the ac the brakes mush up a bit. It speeds up as I hit the gas and when i hit a certain speed it stops until i slow down. I'm pretty sure its not a lifter because it will go away and come back. No Idea.
Any thoughts?
