Not necessarily an IAC problem. 1500 rpm +/- 100 rpm is normal for warm up idle in park or neutral. This information is from a 2000 factory service manual.
What codes do you have?

I had a lean bank 1 code after changing fuel injector o ring. Since I did everything that code hasn’t come back yet. The high idle is what’s lingering. I don’t remember it doing it before I replaced the oring the first time. As of now there are no codes
