I am having difficulty trying to figure out what this is (see attached photo). there is hose coming out of it that is not attached to anything. this is in a 2001 blazer 4wd. Thanks for your help in advance!

Yeah I would say air injection as well looking at those hoses. Have you followed the hoses to see where they go? Probably to the exhaust manifolds or somewhere in the exhaust system before the O2 sensor.

Its the A.I.R. pump. The big hose that is not hooked to anything is the air intake for the pump.
