We are trying to figure this one out ourselves and waiting on a response from google. If it were a spam penalty, I'll be darned if I know where to look especially through the thousands of pages we have! I hate to do anything to the site unless I had a real good idea of what it was that was causing it. We rank very well in both msn and yahoo and don't want to risk those and loose everything (unless I do something that is easily reversable). Never exchange links, never cross link any of our own sites, on page factors are most generally typical, seeing others far worse. Internal linking is simple pyramid. Large amount of 302 hijacking from one particular search engine which had 80% of our pages. Old 301 pages popping back in (probably a side effect).
