So I got into investigating my cold idle issue a bit today. The past week she's run ok and hasn't given me any issues until the other morning when I fired her up in -10 degree weather.
The info given to me prior to this lead me to believe the CTS was the cause, however I'm not so certain that is the case.
Here's what happened: Went out and she fired right up, idled fine for a bit (2-3 min) then died. When she fires up she idles high then starts to hunt right before dying. I unplugged the CTS while running, the idle shot way up, then she died. upon plugging the CTS back in and starting her up, she went back to what she was doing (fire up perfect, idle for 2-3 min, start hunting for it, then die).
So, I am wondering (and speculating) about the IAC valve being borked. It seems as if the CTS is functioning properly, and the plug/contacts are clean.
