Eratic Idle?
So I have a modded 06 IX tuned on E85. Ive been daily driving it since November without issue. A few weeks ago it rained very heavily and the idle started bouncing between 1100-2000 at stop lights. I didnt get a chance to look it over. The next day it was fine so I assumed something got damp and didnt like it and once it dried out everything was fine. Fast forward to last tuesday. It got EXTREMELY humid out, but no rain. Again the idle started acting up. Well, its friday now and its still doing it. Im going to look it over when I get home this evening to see if I can find anything obvious (vac leak maybe?) but wondered if anyone had any ideas on where to start looking. No CEL and no codes pending.

MAF or speed density?
What is your intake system like? (box, cone filter, etc...)

ETS intake with a Perrin filter (looks like a black q-tip), MAF tuned.

If you go WoT and then when your revs are high and drop it into neutral will it hang high in the rpm?

Its only done that once , it hung at about 2100 rpms for a matter of 3-4 seconds. Its been awhile since it did that though.
