Do you have a catalic converter? My first guess would be that it is dead.

Yes, I do have one. I'll check it out this weekend. Any other ideas...suggestions?

Whats your O2 readings. A good working cat should have less than 2 percent o2 at both speeds. If you have high o2 percentage I would say its def. the cat converter.
