Hi Mike,
I looked at the article but (since I replaced both fuel pump & Filter recently) feel my problem is of a different nature.
The rough Idle is intermitent, and most noticable as the car slowes to a stop.
My thinking, based on searching the forum and talking to a bunch of people, is that my rough Idle is more likely from a leaky ditributer, the airflow meter body or a EHA valve .
All these cost a nunch to replace - so I am holding off until I can figure this out.
