Run codes. There's really only a couple of things that effect idle. Your tps, the iac, and possible timing. Also if your idle screw is setup wrong, the computer pulls timing to try to make it idle lower.

Basically, run codes, see what pops up. Then chec vacuum lines and fix any bad ones. Then try to do a basic idle reset unplugging the iac and test to see if it is working properly.
