So I'm going to say it starts fluctuating after you warm it up? When you first start up it'll idle at say 2k nicely. After a little bit, it drops to 1k up to 2k back and forth back and forth. Check your fast idle.

IAC is a good one too, check that by unplugging the iac when the car is one and see if it idles smooth.
