This doesn't seem right??? moving the whole dist should just move both the body and shaft together. You must have a pretty marginal situation. I have never had a dist with significant side play. I HAVE had a set of 72 trigger points that seemed to be mismade and gave me problems. I bent the points as you did at first, but still had trouble. They were just shaped wrong and replacing them with another set that was just as old cured things completely. > Combine that with worn nylon riders on the contacts and you have problems.

Sorry, I don't have new bushings, but I do have good used distributors. > Another thing I discovered... the cold idle was getting unreasonably rich So I pulled the aux air > regulator and found they are not all created equal!

There is a cold temp where the valve should be fully open.

All generators crap out at low rpms; that's one of the advantages of alternators. I think the FI was built to take advantage of this, however, by helping it to richen while starting and at idle. The loping idle is not related. It is the result of the idle being too fast, so the FI senses that the rpms are above 1400(?) and yet the throttle valve is closed, so the fuel is shut off, rpms drop. FI senses that rpms have dropped below 1000 so FI kicks back in, rpms rise. The fix is to reduce the idle so it never goes above the upper trip point. If your aux air regulator is set wrong, this may be impossible to achieve at all temps. So you may need to rethink what you have done to yours. The goal is to achieve a constant idle speed throughout engine warmup.
