Well thanks for all the help. I got the problem fixed. I wound up just taking the derailleur off. I think it was slightly bent so I fixed that and cleaned and de-gunked the derailleur. I put it back on the bike, made my adjustments and everything works great and the Miyata is back on the road.
Sixty Fiver, I wish I had read your post before I took everything off. Putting that cable back through the derailleur was a pain in the butt.

Thanks for the help everyone
