Hello Zoltan,

I don't have my '84 anymore so going from memory.  Spec idle as I remember is
950 rpm when warm, everything on and van in neutral or park.  I ran timing at 5
deg. BTC.  When you put it in gear,electronic idle stabilizer should bring idle
back up.  Idle stabilizer advances timing in distributor to keep idle constant.
Remember that when you restart the van, the O2 sensor is cut out for the first
two minutes.  I had one bad experience where I had to drive my van from FL to
Macon, GA, with a bad O2 sensor.  Idle would drop off once I had to stop for
traffic lights.
