My '91 had the problem. (Intermittent loss of power at speed after about an
hour of continuous driving, generally in cold weather.)
  I installed the capacitor, and it seems to run smoother and idle down better,
but I am not sure if the main problem has been solved since I haven't taken a
long trip in cold weather since.
