I'd check the throttle plate like I mentioned earlier. You may well have to tweak its positioning, and your idle may be perfect. I'd do that at least, before I returned it. There is a throttle set screw on the side of the TB.
Ok at the risk of jinxing myself I "may" have sorted it out. time will tell when the car has sat overnight and is cold.
I adjusted the throttle screw like you said to do. I have the car warmed up and idling maybe around 850-900ish in park and 750ish when in drive and my foot on the brake. When it starts up initally it goes to about 1-1100k and then drops down. I do notice the idle fluctuates when in park (wonder if thats the potentially bad IAC). When car is in drive the idle is smooth and steady. I may have to do some further adjusting perhaps...dont know what will happen with a cold morning start.
Of note, the results above are also including putting the spout connector and the FPR vacuum line back on.
