help me find this rattle

i have an 05 double cab 4x4 when it is cold there is a rattle that sounds like it is right in front of my feet,it is loud at low rpm but when you accelorate it stops. when truck warms up it stops.i have checked c.a.i. thanks

 

Is there a wiring harness or hose or somthing you could put duck tape on? My VW had a rattle like that (on vent) bugged me until I gave it my daughter and got the truck)

 

it sounds like a loose heat shield but i cant find one , it is louder in the truck than outside

 

I've got a similar sound. I've been searchin for it forever, but can't find it. Mine doesn't go away when it warms up though. If you figure out what yours is, let me know so I can check mine, too. It's at very low RPMs, and at first sounded like it was around the passenger side fender area. I've looked around and can't find anything that would be makin the noise. Pisses me off.
