William,
I have noticed this too. Perhaps this was the inspiration for  the inventor
of the "AFM capacitor modification".

Subject: [VANAGON] 060412 AFM question

Over this last weekend, I did some smog adjustments.  One of those was
tweeking the AFM.  For those of you who have experience with the AFM,
should the wiper be moving (jitter or oscillation) of about 1/8 to 3/16
of an inch at idle or should the wiper be pretty stable?
