IAC not responding like I think it should 7747

You are welcome. If I understood better what you are trying to do here, perhaps I could point you in the right direction. I assume you are trying to control the idle speed. what idle speed are you trying to achieve? Remember that with that cam, you may need to idle a little higher. My guess is somewhere between 750 and 850. Anything below 500 automatically will invoke stall saver and move idle to 500 minimum, and I am not sure if the cam you are using will like idling that low. Also, there are a lot of conditions that may or may not adjust the IAC postion (like the park/Neutral switch, or A/C which I assume you don't have)

Actually, my idle is great at operating temperature. It stays consistant at 800 RPM (0 IAC steps). No I don't have AC and I don't use the Park/Neutral switch.

The part I'm trying to adjust is the idle when the engine is cold. I want it to idle higher.
