That looks like it could be the vacuum supply connection that supplies vacuum to the HVAC actuators and the 4wd system.
A large vacuum leak could cause the engine to run incorrectly due to the mixture being off.
To check if I am correct, follow the hose that is connected to that rubber elbow and see to what it connects. You might find some other rotten vacuum hoses too.
I have link to a page that someday I'll be submitting as a stick on how to replace those hoses on the Blazers with the 4-button transfer cases. It is similar to the ones that have the 3-button transfer cases.
