Weird. It was something YT posted a while back. It could be a result of a lingering issue with my car - that first start up of the day it also stumbles to life. After cranking and the first cylinder fires it will stumble/miss for a few rotations before all cylinders come online and the idle smooths out. This takes maybe 1-1.5 seconds and happened long before I changed the transmission. In fact it happened before I changed engines, although it went away for a while.

On really cold mornings even in FL, I have the same problem. My built engine just won't have an AACV at all.
One thing you could do is crimp the hose that goes to the AACV to limit the max amount of air it can flow.
All true. The SVX throttle body is just setup in such a way that the car will feel very responsive starting off (probably to help make up for the slow-off-the-line final drive) with the automatic. This is something I've noticed as well. So the slightest tap on the throttle has a little bit bigger effect than you might intend. I've been used to it for a while now. And I also noticed that the EG33 is quite happy running at lower rpms, and has plenty of torque to get the job done too.
Does yours ever stall when you clutch-in?

Temperature seems to have no affect on this. The car lives in a heated garage, so it's never below maybe 18*C (normal indoor room temp or a couple degrees cooler) and does the crazy idle thing, but also sits outside in near freezing temps at work and starts properly.
I do need to adjust the AACV to cheat the system a little. I stripped my throttle body down completely a couple years ago to clean/shave/paint it and discovered while putting it together that taking it apart was a very bad idea. The plates are a ***** to get aligned perfectly, and as a result it idles a little higher than I would like.
No MT stalls for me!
