If you still have a PR4, you are not penalized. You are still in the Google index. If you move your site over to a new domain without fixing whatever problem you are dealing with, you're wasting your time and money. You'd be better off spending the time to figure out what is causing your site to be ranked poorly and fix it. Otherwise you're just moving the problem to a new location.
