Bob,

It might not be the AFM unit. My son has a 93 Fox with Digifant II and it
would cut out at low RPMs, especially slightly off idle. There is a
throttle switch which enriches the mixture when the throttle is opened
(like an accelerator pump on a carb). His switch is apparently bad. I
disconnected the switch and the cut-out problem went away.
