Try cleaning the throttle body with good quality carby cleaner, chances are your throttle is stuck open alittle bit.
Does the car blow smoke, if so what colour.
Just my 2c worth

mine also seems to have 3 idle speeds: 2k, 1500, 800.
yours seems to stay too high for way too long, it should drop down as soon as the engine warms up.

if the idle screw is turned all the way down then something is faulty, it should be at least 1.5 turns up
cant be bothered writing this for the hundredth time so just click the link....

OK kick me if im wrong but wouldnt this just be the cold idle ?
and also seeing as though 2 other ppl have a very similar "problem" i would think even more so that its just the cold idle
and 10 minutes sounds about right as most cars take 10 minutes to reach Operating Temp when left idling....but it should be much less if your actually driving it
am i wrong ?

I have a 100kw 4AGE small port in an AE86.. First start when its cold gives an idle of about 2,000rpm.. after about 2 minutes of idling it will drop to about 1,500 for another 5 mins or so, then drops to 950.. All 4AGE's i've seen do this. Although yours seems to take a bit longer.. Is your thermostat working correctly? On the 100kw (not sure about other 4AGEs) the cold idle is controlled by a wax pallet in the throttle body (water lines run into it), so the engine will continue to fast idle until the water temp rises to op temp..
When i did my conversion with this engine, i found it idled around 2,600rpm for a LONG time, found that the gasket inbetween the throttle body and the plenum was damaged and leaking. Might be worth replacing that?
Cheers
