There are very few cars that I've worked on that I couldn't get right,
and you own one of them.  The best results I had were changing the
IAC to a different pintle design.
    If someone gave me one, and I had to drive it.  I'd go to the library
and find the newest closest congifuartion, of ecm/pintle/IAC, and
then go to the nearest recycling center and get those pieces.
Drive home, and try them.
  Other choice is having some custom pintles made, and trying them.
MHO is there is something basically wrong with the software/hardware of that
car.
