As my saga goes on.  I checked my O2 sensor voltage, now that the idle
had settled down.  On hot engine (off) I disconnected it then turned on
the engine to check sensor voltage.  With the sensor disconnected it
started to hunt idle again, not surging as bad but still definately
wrong.  O2 sensor would fluctuate between .5 on one side of the idle
oscillation to almost 1.0 on the other end.  Put another half turn on
the screw (clockwise) to see what would happen.  It stopped fluctuating,
but the idle was not strong and the sensor stayed at around .9v.  GRRR!
Any further help guys?  I'm really getting frustrated after so much work
to fix the heads to be held up by this kind of stuff.
