Ok well I dont know any more details I havnt done anything to it when I get on it hard and I let off it kind of backfires due to the gasket I have to fix and then theres this loud rattling like loud rattling and it sounds like its in the engine bay areas or maybe behide it its not whiney its semi deep

If it sounds a little like big tin cans bouncing around it might be your catalytic converters.
Just a guess but running rich will cause backfiring and will melt and glob up your converters.

wow thats great.....no i think the back firing thing is the gasket and im hopin the burning is the simple green

but lets say ur right how do I check to see if shes runnin rich and if they are clogin up wont the exhaust be REALLY hot

also how do i turn it down so it doesnt run so rich

and if it is can I just punch out the cats? wait i have to take them off for that can I just punch holes in them for now I dont have the money to get them replaced

because now i think about it, it does sound like tin cans i think

It could possibly be your exhaust hitting somewhere around the rearend area, that happened to me.
