took off the iac, and egr for cleaning/lube.
iac was cleaned again and this time worked it up and down lightly with some lightweight oil. seemed to function a lot smoother.
egr was moderately dirty inside, cleaned well and oiled plunger.
after reassembly, and battery connection, stated up and after a few minutes idling it seemed to have improved pretty much, even in drive - but especially in park.
the shaking has gone down noticably, and also notable smoother idle.
still the same problem, but far less. its almost to a bearable point now -- either that or it was so bad this improvent has me temp hyped out.

any suggestions, or was the post too long heh.
it almost seems like when i hold a few rpms in park, i can barely make out small stutters now and than - not enough to really notice, but there.
