The 87 syncro is still buckin like a stalion.  Most of
the bucking is at highway speeds, cold or hot, but it
will buck briefly in 2nd or 3rd gear with high rpms,
esp with a load.  bucking started off very sporadic,
and is now pretty much constant.  Here's what I have
done so far...

- Checked temp sensors in place and not loose.
- Fixed o2 sensor (wire was torn in half).
- replaced throttle switch with new one.
- tightened (then untightened AFM).
- removed AFM aftermarket wiring harness (bucking got
worse) put it back on.
-replaced plugs, cap, rotor and wires (not bosch
wires, but oem from bus depot).
- didnt mess with timing.
- checked obvious grounds

Some other symptoms -
- Think the alternator is going  bad - OX and battery
light on most of the time now.  Alt is 2 years old,
only 10k miles on it.
- high idle when cold - up to 2500-3000 rpms.
- average idle when warm is 1200-1400 rpms.
- afm shows warn tracks on the carbon thingy - cant
tell if they are badly warn or not.

So, today I fixed my rat chewed digitool and fired her
up.  heres the numbers while hot at freeway speeds:

Throttle switch led and Fi led work correctly when
idling and wide open.
temp 1 - hovers around 1.24/5 up to 1.28 once
temp II - hovers around .14/5
OX - fairly wild, occasional - to 6.3
AFM - around 3.5 - couple of checks showed 3.8/9

When the bucking was occuring, numbers seemed to hold
steady, although FI light flicked on and off wildly.
Also, battery level down to low 11's during bucking,
even 10.9.  still bucked a time or two at battery
level of 12+, but when bucking was bad, battery level
was always in the 11's.

Do these numbers/symptoms say anything to anyone?  I
cant find my digitool diagnostic numbers at home or in
the archives, and my URL for Darrels site is out of
date.

Thanks,

Jeff
