Having some issues with im iacv on my z6 check engine light code 14 on and idle hunting until at operating temp. Ive changed the iac with a known working good one didn't change a thing. Adjusted he fast idle thermo valve (fit valve). any suggestions

Did it just happen out of no where or have you done any mods lately.

new motor was put in started shortly after motor was in

If the cel is on for it its a wiring issue. Check for battery voltage. check the ground side. with a dmm!!! not but touching it and looking at it.
