Default Stuttering Warm Startup for 10 secs

This never happens during cold start, but when warm start up, there is about 50% chance that the engine idles at a very low rpm (maybe like 100-200 rpm) and when I give it half throttle it slowly goes up, and after about 10 seconds of revving it up, the idle is fine.

Any idea what my problem is?

I already have perfect 14.7 AFR idle when this problem does not occur or after several seconds. TUned with uberdata.

sometimes uberdata wont control the obd2 iacv, if you wanted to take the time to swap over to the 4-wire ( ithink, might be 2) iacv then that problem will go away

sounds like a eacv(electronic air control valve) at the back of the intake manifold is not working properly, i had the same problem when i ran an automatic intake manifold and just let the eacv hang with the coolant lines connected and wire plugged in. Maybe try a different eacv or just clean it with wd40?
