well...i just found out that the cat on my car has warranty. It doesn't have a recall, not on my car...but at least it has a warranty. So, i'm taking to dealer where they're going to check if cat is the problem...and maybe replacing it. Now i'm just hoping that cat is the problem, so I dont have to pay anything to fix this stupid car. I already put too much money into it.
Anyway, i'll post what the problem was as soon as i find out.

thanks for all your help!
