When I start my car after sitting, it seems to idle up and down for a bit, but smooths out when it's warm. I'm getting no SES light, and the TPS is adjusted properly. However, I had to fully back out the idle adjustment screw to get it to idle down this low, is it possible my IAC needs adjustment? I've just finished putting the intake back on, after replacing the injectors. The intake, TPI and TB gaskets are all new, and I don't think I've got a vacuum leak - I tried spraying carb cleaner around all of the gaskets and TB, and it didn't have any effect. Here is a video of what it does from a cold start. The whole time it seems to wander back and forth between 500 and 1000RPM, almost dying a couple times. I wasn't touching the throttle the whole time, except for at the end, I give it a couple kicks, to show that it has good throttle response:
