TBI 350 Target Idle Speed

Don’t think base idle has ever been messed with because the plug is still there,
Coolant temp is reading correctly based on the scanner. Ac is off, transmission is a manual for that won’t affect it, and what’s cranking idle air? Is it possible that the base idle needs to be reset? I don’t see how it would get out of adjustment unless someone messed with the screw?

If it was base adjustment the requested idle would be low and it wouldn't be able to get it that low. I don't know the BCC codes off the top of my head, is that a manual calibration, or a swapped truck?
