Take off your air filter box, crack the throttle wide open, point a flashlight down there, and have a look. See any oil? Time to yank the intake.
Get yourself a spray bottle that will do a fine mist. Fill it with water. Start the engine. Squirt things. If the idle changes, there's a leak.
IAC is on the back side of the throttle body. Yes, you can take the TB off, remove the IAC, and clean them both. Get a new TB gasket BEFORE you take it off. (yes, that is the voice of experience....... ooops.

O2 sensor, or fuel problem (pressure/injector(s)).
Do a fuel pressure test, and the vac leak test.
If both pass, then it is probablythe O2. Bad thing is that if it is NOT the O2, you just spent money on those sensors. THey are not cheap. ESPECIALLY if you have a california vehicle like mine. It has FOUR O2 sensors.
I hate california. Even though it was beautiful and I liked the farmers markets and fishing.
