OK guys this mod officially didn't work for me! I guess my IAC works better when it is connected <img src="/forums/images/graemlins/drunk.gif" alt="" />

I didn't have crazy idle problems but I do have annoying RPM hold when shifting IF the AC is on.

Disconnecting the IAC caused my idle (no AC) to drop from 1000 RPM to about 800 RPM, which is a dubious benefit... I don't see how this is such a great thing. Then, when I turn on my AC, BLEH, the engine stumbles and dies. Horrible.. Not worth it. BTW I drove around with the IAC disconnected, and with the AC off I noticed NO difference in revving or the way the car drove. With the AC on, the car would die when I came to a stop, but the RPM hold was gone. I'd rather live with the RPM hold; I think this is a pointless mod for me.

By the way, in case you wonder, it was about 105 degrees F outside when I was doing this testing, so it's not a matter of cold weather... I am not sure how you guys got better performance from disconnecting the IAC plug but for me, this was the kind of mod that only screws up your car <img src="/forums/images/graemlins/drunk.gif" alt="" />
