The key in the cam gear is only there for the alignment until the bolt is tightened. It doesn't really hold the cam gear in place once the bolt is tightened. Same for the crank pulley too. The key can break if the bolt gets loose enough for it to turn.
I'm just curious how the engine sounds as you said it ran smoother for a short while when you opened up the throttle. I'm about out of ideas. If you take it to a shop the first thing they're going to do is check the timing again and check the compression I bet.
