The Google CSE results are completely driven by the CSE that you have setup. You need to go to your Google account and configure the CSE results. You should be able to exclude either some sites from the results.
If you recently removed the pages, google should eventually remove the results from the CSE, and the converse is that new content will not show up in the CSE results for a few days (or sooner if your site is indexed regularly).
Mostly, this isn't a Drupal issue, but a Google CSE issue.

I've installed Google CSE on a site and it's returning waaaay too many results. It's finding pages that don't exist anymore, test pages and others. How do I stop Google CSE from searching its cached (and now nonexistent) pages? I can't find anything on this topic anywhere so help would be much appreciated.
Many Thanks!!
