My stupid single jingle still won’t idle.

So far: cleaned IACV, replaced TPS, and used the starter fluid method to check for leaks in the vacuum. Generally it will start up, rev to around 2k rpm and then after about 20-30 seconds drop way down and sputter or die. I’ve tried adjusting the idle with the IACV but it seems to have no effect.
