Low/really rough idle when warm

[92SportSedan]

Long time lurker here. My car has had the issue for awhile, I thought it was the leaking uppipe but I fixed the leak today and it's still an issue. In traffic the idle drops to like 150-200 and bounces off 0 shaking the car and almost stalling. I wanted to get some ideas before I start buying parts, my initial thought is the IAC may be bad/dirty. I recorded a video in my driveway but when parked it doesn't seem to be as bad but the car still shakes. It's stock other than an axelback muffler. Thanks for the help

Fixed the issue for the most part, the IAC flap was sticking when opening up. Seems like it's a common issue because I've owned the car almost 5 years and the gasket looked new so the guy before cleaned it too. Car still idles low after putting the clutch in but doesn't want to stall which is good.
