Its a screamer!!!!

I have a 89 notch with 200K plus as well as the 92 in my sig. Of course, the trusty old coupe runs like a bear, except for one problem.The problem is with the screamimg idle. It will be fine for a day or so, then out of nowhere the idle screams up to about 2 grand or so. The two ways I get it to go back down are to flick the key so it stalls and re-starts without the starter, or to go under the hood and unplug the IAC motor. So, if i reset the idle, it does not help either. In a few minutes, it hauls a@# back up to 1500 or around there. I changed the IAC and it did not help as well as the TPS. I do get a check engine on and off, but no patterns. Any ideas?
