SEO And Iframes

[royals]

I recently added iframes to the sites which were ranking page one on google. after 3-4 days both sites dropped to page 2 and 3

i am very much sure that adding iframes was the main reason to this

now i have removed the iframes, so does anyone thing that my rankings will come back?

i think if google crawls the site again and see no iframe, will my site be at page 1 again?

please answer this
