The other common one, check the hose that goes from the IACV to the intake pipe. That one is also easy to bump when you change the filter.

BTW does anyone know what the idle speed should be on the 2.2 legacy? It runs good but may be slightly low in the 400-600 range;the lower amount when ac is off the higher when ac is on. Is there an adjustment on these aside from the 2 throttle cables? It is a manual shift and never dies but I thought the emissions test needed a higher idle. j
If it idles smooth and doesn't have any problems, leave it alone. There's no idle adjust. It's controlled by the iacv, and if it's not idling right, it needs to have the valve cleaned.
If it works, don't fix it. The tach on my old 96 read low, I thought it had a problem. But a scangauge actually told me it was idling dead nuts at 700. So it's probably fine.

AC on should come up to maybe 750.
No adjustment for idle speed. If you make adjustments to the throttle stop the ECU will just bring the speed back down to the proper setting.
The best thing you can do is clean the IACV with throttle body cleaner or seafoam.
