High idle after replacing IAC ?!

Let me start by saying the car is a 2003 Mitsubishi Lancer oz rally.

Previously my car would die on cold start and have high idle on hot days I also got a code for my IAC so I replaced it. After replacing the IAC my car started good on cold starts but when I turn my steering wheel my rpm go up like 1500. When I turn my heater on or AC my rpms also jump about 1500. So my cars reving around 2500-3000 when I do those things.

when I unplug the new IAC the idles donít jump doing those things. Iím so confused, has anybody had this ishue?! I gotta be doing something wrong!!!
