speratic RPMS and rough idle

[95eclispe]

So for a while now my car has been idling all over the place. one minute its idling at 1000 rpms then it increases on its own to 2000 rpms without me hitting the gas and stays there for a while before dropping back down to 1000 rpms. other times it drops below 600 rpms as if it wants to turn off which sometimes it does. If it doesnt turn off it increases rpms on its own but when it does turn off from running it wont turn back on until the car cools down. Im not sure if they are completely different topics if it runs hot it wont turn on until the car is cold again so i cant run into the store unless it stays running. Any ideas what the issues might be? or if anyone has had some similar issues?

Have you checked your IAC/ISC/TPS with a multimeter?

the last time i took a multimeter to it the numbers were ok until it drops idle then lowers until the rpms on the car pick back up.
