THis is driving me nuts. (84, 1.9)
I have a surgin' issue.  It has been haunting me since the Clinton
Adminstration. Here is what is doing and what i've done.
Slight surge when driving. Idle is smooth at 1000 or so.  while in neutral
if i accelerate to 2000rpm and hold it, after 30second or so it will go to
3000rpm for 15 seconds or so and then back to 2000. Repeat every 30 to 40
seconds.  Grounds- all polished and some replaced for kicks.  AFM, track
cleaned- 40K on it.  Oxy sensor- new. Temp2- new.  Thermostat- new,
throttle switchs turn off as soon as you move the accelerator cable and
when fully open.  Air filter new. Ohhh, new seat swivel.  All vacuum lines
replaced (all that i could find at least) fuel pressure regulator replaced
with a used 'good' one from a list person (traded for quart of my honey).
Plugs, cap, wires, relays ok. COmpression great.

Not done but could they be the issue?
Crack case ventilation
Idle stabilizer (but the idle is stable)
22uF capicator fix (details needed on that)

I only 1/2 trust the bus because of this.  I've searched the archives for
this and got mostly the things i've already done...
