Ok so i think i have pinpointed it....

The cover over the fuel injectors... i am not sure if thats the exact name for it ... but right when you open your hood the dam plate that says vtec on it... ok so everytime i rev the engine and it starts dropping in rpm it will make a rattle noise like something is rubbing on it... anybody have this problem or heard of it?

I have the same thing.
I scoped it out and it seems that the engine cover is just hitting the manifold.
I guess the idle drops too much.
Mine did it too after the first time I took the manifold cover off. Make sure your bolts are tight.
yeah i thought it was going to be that.... so basically just freaking tighten it up
personally, i just took mine off. it got annoying.
yeah but isnt that needed tho? so shit doesnt get dirty

No. It is purely cosmetic.
Remove it. It lends a tacky feel to very pretty motor compartment. None of these plastic cosmetic parts belong on a K20.
I put a couple spacers under mine.

While it is pretty much just a cosmetic piece, it also muffles the sound of the injectors a good bit.
mine did that too but after shifting it around a lil bit i got it to quit rattling and tightened the bolts down.
u mean the intake manifold cover
