if the air filter clogged up, the IAC port might have gotten it too. note the TINY little hole in the bottom of the well. clean the well and the pintle of the IAC, but don't push, pull, twist the IAC. maybe even just replace it. about $40-50 at local parts stores.
replace PVC valve and clear the hose to make sure its venting crankcase pressure.
