Continuing idle issues with 1995 EJ22 engine (1997 Legacy GT)

That code points at the IAC. You can remove it, and see if it's dirty, clogged, gunked up. Can also double-check the connector is tight. With engine running, try wiggling it's connector, as well as the harness for it. If engine straightens out, find the loose connector or possibly wire break, including chaffed wiring. Could have a gasket leak at the sensor, bolts are loose for it, etc.
If you replace, be sure to get a new gasket for it.

I think that you are very fortunate to get a code. You should pursue the actions recommended by Bushwick. I've never had a fluctuating idle with any of my 2.2's so I can't really help. However on my 2002 2.5, I've had it, and it is very very difficult to correct without a code. In that case, I eliminated 95% of it by replacing the knock sensor with new OEM.

Yes, It was totally a bad IACV. I put a used replacement on and everything returned to normal. The idle seems a little rougher in gear, but nothing terrible and idle speeds are normal with no fluctuation. The noise in the intake is gone as well.
