My sr20 with a bad idle, I tried finding similar videos online but I couldn't really find someone with the same idle problem. It seems like after the engine is warm the idle kinda sorta levels out but it still idles fairly high. Only mod is T28 turbo ISR manifold, ecu is #62. Cleaned my IACV, also replaced spark plugs, i'm trying to narrow everything down so I don't just throw parts on the car. I don't think it's the MAF but I could be wrong. Also I tried adjusting the screw on the IACV and the idle still remains high.
Heres a video of the car idling , then mad unplugged, then plugged in again and a few revs.
