Cam timing chain, timing chain tensioner, or tensioner arm. It may be that accellerating temporarily pulls the slack out of it and that at idle it settles down, etc. 4.6's are notorious for cam chain/hardware "ticking" noises. Then again, I might be wrong.
OK, after I posted this I saw that there is a post in this section above the line which addresses fixing the ticking noise in a 4.6. He describes what I was talking about here.
