It didn't quite sound like it was running on 5 cylinders. In fact, it almost sounded worse. Listening to your car I've been thinking about what it sounded like and I just can't figure it out. Did you do the timing belt? I don't know what it sounds like with a cam being off one tooth, but I guess that could be the possible problem. Not sure though. Very strange sounds your car makes =( Keep us up to date on what you find out.
