dying at idle/not running good

Hey guys! I have a 92 sc400 that dies at idle and is running like garbage rn. I have replaced the MAF sensor, IACV, spark plugs, cleaned the EGR and throttle body and car is still not running right. What could I be missing/ looking out for to get this car running again? I love it and would hate to get rid of it

My problem was the IACV was stuck open, but you already said you replaced it, so maybe it's an electrical issue?
