Exclamation Air Injection System Problem

Hey, I'm new here.
I recently bought a 1993 ford f350 with a 460. Its had some issues but the one that's kicking my *** is the air injection system. For some reason the computer wants it to constantly pump air into the front of the cat, even after it gets to operating temperature.

*Air injection diverter valve- Put vacuum on it and it switches, yay exciting
*Air injection diverter solenoid- 12v switches on, closes cross way to port when no power. No leaks or anything.
*Vacuum line connections- Yup, all set up right
*Electrical- No shorts or resistance. thank god for easy access

*Computer, worst case scenario. I got nothing else

Lastly, if anyone has any ideas please throw them out there. I need to know this so i can safely put a new cat on and finally pass smog. Thanks for your time and hopefully your help
