I don't think that will eliminate the CC problem. I really believe you have a vacuum leak. That would cause a low, rough idle and cause the CC to lose vacuum pressure and slowly drop speed. That is my guess at this point. As far as the idle, 900 in park or neutral and it should be around 6-700 in gear.
Let me know what you find.
