Celebrated too soon. It probably needs a p/s pump. The pulse is still there, especially at low revs turning right when cold in the AM. I have a p/s filter that I got for my previous wagon, but never installed. But with the price of hydro-fluid, and the fact that these pumps wear out, I may save the filter for the next pump. Any rebuilders or rebuild kits out there?
Any leads on a used pump?

DDH and 1stbenznc, your cat diagnosis reminded me that I've seen the same low-revs-only, and engine-dies symptoms on 3-4 Ford fleet vans when they need a cat. And replacing the clogged cat cured the symptoms. But I'll be hoping that just cleaning and tightening your fuel lines does the trick.
