I have cleaned contacts in the distributor cap, set timing, even tried
advancing it a bit. I have replaced the malfunctioning vacuum advance. The
two relays are new. Idle stab is doing its thing. No terrible vacuum leaks.
I also tried unhooking the o2 sensor. My next step is trying to locate
someone with a working afm to try, unless anyone out there has any better
plans.

Thank you for your continued help. The van is pretty near undriveable in
this condition.
