Since it is a compounded problem fix what you know is broken first, that idle valves are like $20.That will help make finding the other issue easier.For hunting idle or high idle after warmed up, pinch the hose that is before the throttle.
If you were spraying recently go over the easy stuff. Plugs, and the rest of the ignition. Do the easy unplug test on the injectors one at a time, see if the car idles the same or worse. Worse means it is fine the same means it isn't working. Then move on check the TPS, O2, and MAF one at a time. Check Fuel pressure maybe a compression test if you still haven't found it. You can pinch the hoses coming off of the valve cover and watch for idle changes which tells you if it is a vac leak. Move on to the power system next check battery and alt as well as grounds
