4.0 V6 idling issue

Hey guys, my 1997 ford ranger has randomly started with a lower idle than usual, usually takes a couple attempts to start and is hesitant from stop and starts. I cleaned the IAC valve and sensor, cleaned the mass air flow sensor, checked air filter ( it’s good ) and tested for codes. I don’t think any of these codes would relate to the issue I’m having but if anyone has any ideas on what to do next I’m all ears. I’ll attach my temps aswell

Check your purge valve for proper operation.
Check its feed for power, etc. I don't know the pin layout for it.

Have you ever changed the fuel filter or given the fuel system a dose of Techron Concentrate?
You never know and could get lucky.
