ive been heariung a rattling l;ately coming frm the bottom of my car, it sends a vibration thorugh my car wen it idles sometimes and usually comes wen i car is warm... can it be the heat plate?? if nto wut else can it be??

 

it's your heat shield, just get rid of it

 

whats the purpose of the heat shield, and y is it not necessary?

 

^ to keep you from severely burning yourself on the manifold, you don't have to just take it off, it probably just has a rattle from a loose or missing bolt.

 

mine did that before, it was because during install i bent itand so it was hitting the piping, i just bent it back and its been fine
