you may have a bad O2 sensor if that was a known prob before
ripping down the street with an unknown problem not really the best plan~
Wet filter could have allowed some water in- not enough to hydrolock the motor (lucky you!) but enough to get some mixed in the fuel and contaminate the IAC-- on the bottem of TB assembly
I would pull the TB (needs new gasket) and flip over- remove round cover plate and clean disc under it- thats the idle air control valve

Unplug the IACV harness and apply some dielectric grease in the connector.

ahh inspect for problem before ripping apart--good call Kris~
