ok, a few comments
1. the tube that does not have any relation with the IAC is the vapors from the oil sump.
2. I did the test. It started a little more difficult but when I repeat it with the gas pressed slightly wile cranking was ok. Stable idle, large improvement on throtle response, noticable improvement on the speed of increasing revs.
3. refering to Daves' remarks could engine imrovements reduse the effect? ex. I run stock air filter Dave has KN e.t.c.
