The thing is, my idle speed fluctuates between 750 and 950, it cycles up and
down, up and down, and this is the closest I can get it to the 850 plus or
minus 50 idle suggested by Bentley, no matter how careful I am with the idle

It makes no difference whether I have the advance and retard hoses on or

Bentley says that for an uneven idle, I should check the connections and the
sensors. All my connections seem fine. Not sure how to check the sensors
without the Bosch tester, and besides, when Jim and I went over everything
last summer, all the sensors checked out fine.

If this is normal, why? Bentley doesn't seem to suggest that this should be
normal. Could this be a trigger point problem?

If not, what diagnostics should I do?

Again, my charging system is fine. I get 12V at the fusebox wrt ground with
the key off, about 13.5V with the car at idle (prob not completely warmed
up), and 15V when I raise the rpms, just like Jims FAQ says I should.
