automatic RPM kick down when cold on Series II
Whenever I start my 99 on a cool morning (less than 40 degrees) the engine revs at 1500 RPMs. The higher RPMs on the initial start are to be expected, however, it will stay reved at 1500 RPMs indefinitely unless you tap the gas or put the car in gear. It acts very much like an old carberauted engine with a choke. Is this common on the Series II engines or do I need to do something to stop this from happening??

Mine does that as well. Strange.

That'* just the startup, every car i've started and not used right away does this. Helps warm up, keep the alt running good to charge the battery etc as far as I can tell. With my stereo pushing hard, my alt dips down in voltage a little at warm idle, but @ 1500 it doesn't dip at all.

My 93 does it, it seems to have a multi-stage system. It starts out very high, and then like you said after 10 seconds it may drop some, but not a low. Maybe like 100-200 RPMS. Once i get in the gas enough, or start driving it'll go down. It'* generally still at warm up on mine when i'm done backing up.

Mine also does idles at 1500 rpm cold, but after it has warmed to about 160 degrees, the engine will throttle itself down to the normal 800-900 rpm idle. I don't know if this is consistent, but I just tried it today. Normally I don't even let it idle long enough to find out.
