My AFM was interesting - I did not check it with voltage as specified in
Bentley, I just measured the resistance.
The resistance was not linear on mine. But I plan to recheck it.

I'm also going to try the capacitor fix, but rather than mount it in the wiring,
I plan to see if I can just add it internal to the AFM.

The problem I was having was that after 4 hours of freeway driving, the engine
would go into limp-home mode.
(Would be okay if I floored it - but trying to keep a constant speed it felt
like the ignition was cutting in and out.)

Does the protraining manual give the resistance measurement that are expected?
That would be good info to share.
