Have had this same problem on my '94 100.  Make sure the arm is bolted
down tight enough.  I've also bent mine in a bit more to solve the
problem.

Check the vacuum line hoses. At that age, they are detiorating.  You may
be getting an intermittent lean condition.  Carefully inspect them, as a
small crack may not be very noticable at first.  Not sure if the '95 V6
has the same lines but, on mine, I've had trouble with the rubber and hard
plastic lines on the top/driver side. (in the channel under the engine
cover between the valve cover and the intake manifold.)

I don't have a link handy but you can pull the codes by shorting out the
OBD-I terminals under the hood.  You should definitely do this, since it
will save tons of time by avoiding the random troubleshooting.  Depending
where you live, there may be a lister with a ProDiag or VagCom that would
be willing to pull them for you. (I'm in the Dallas area, BTW)
