Good chance it's vacuum line. Also could be a bad actuator under the dash that moves the blend doors that went bad.

Mine did this a while back and it was a broken vac line a good way to test it is to see if your cruise control still works or the 4X4 both are controlled by vac

I would say so, thats not doing your front diff and t-case any favors. Vac pump is below the injection pump, and the lines come up to the fire wall above the injector fuel lines. Check in that area.
