Was in my EA the other day, it was stationary and i gave it a hard free rev. It would not be possible to rev it that hard when driving. After i took my foot of the accelerator, i heard a rattle noise that lasted for about 10 seconds. Sounds as though metal is hitting together.
I am thinking it may be the clutch plate, or around that area.
WHat do you guys think, have any of you had this problem?

I had that problem. It was the cat with broken pieces floating around inside (stuffed cat). Only happened when i took my foot off the accelerator and let the revs go down. Same problem u are having it sounds like.
I had my cat replaced and hey presto.... no more rattling and engine ran better.

it sounds as though its coming from under the drivers seat, around the back and bottom of the block. I took off the flywheel inspection plate and had a look around there, but couldnt see anything that was unusual.
Yep it'll be the cat I reckon. You can either knock the guts out of it (illegal, but who will know?) or buy a new one (expensive).
The easy way to tell is to take it off and shake it - if it rattles, it's cactus.

Illegal can also be expensive (large fines), do the right thing and get another one. If you live out in the bush, and not in danger of gassing everyone to death, you could probably get away without one.
I just noticed you had an earlier post on black smoke out of the exhaust, sounds like a rich mixture, this will kill the cat. When you get the new cat on, get the fuel mixture right or it will go out again.

Get a new cat, do it for a cleaner environment. Car owners are responsible for clean air. I live in New Zealand where there are no emmissions laws but I strongly encourage catalytic converters and well tuned engines for a cleaner atmosphere.
