Hello,

   So, I think I have two distinct problems and
each has some bucking symptoms.

1)  When the rig is cold and wet, like there's
been some rain or the air is very humid, the
engine runs but power is *very* on again-off again
for about two or three minutes then the problem
goes away.

2)  At tach ranges below around 3600, both my wife
and I can feel a very slight shudder, or
hesitation, pretty constantly.  This doesn't
change, as far as we can tell, with weather or
engine temp, etc.  Hiway speeds with tach above
3800 are a smooth as glass and the engine has very
good power.

Things I've done recently:

 - all standard tune-up things replaced except the
   oxygen sensor
 - all grounds replaced, ground points cleaned
 - new ECU
 - new wiring harness
 - 22 microfarad thingy in the AFM
 - new idle stabilizer control unit (I had really
   bad idle)

Any idea's would be hugely appreciated.  Thanks!!
