Help! error expected '}'

Hi, recently in my blog appears the error expected ‘}’ line 12312312332(a really big number) only in my new post, and when I open that post in IE8, when I open that post again in Mozilla the page appears for a few moment and gets blank, I don’t know what to do, I only can see the post in IE (and chorme) but like I said, appears the message errors in page with expected ‘}’.

I tried uninstalling old plugins but the problem stills there, is even worst the situation with mozilla because the page it doesn’t shows.

The rest of the content (old posts, pages) are just fine, this happens when I publish a new post, what can I do?

Thx!
