Dale,
This sounds 100% like the Idle Control Valve (ICV) problems I've been
having on my '89 325i a few years ago. The ICV passed all Bentley
resistance/voltage tests but was still flaky/gummed up.

How do the spark plugs look? Dry and light brown or black and filthy?
Last, but not least, there is a possibility of a flaky DME (a royal PITA to
trouble shoot).
