Sounds like you’re still waiting on parts so don’t fret the idle. A 1500 rpm baseline sounds like fun! I bet she feels like she wants to get up and go. 🤨

if ur ICV is good, your high idle is due to either your MAF or a vacuum leak.....

 

Ill give the vacuum lines another look. I think the MAF is good because whenever I unplug it the truck runs like garbage so I suspect it still works. Im just waiting on the OBDII to laptop thing to try and reset the base idle.
