vacuum leak, most likely a large one… if you do not have a lot of tools, use a spray bottle filled with water and spray water along the bank 2 side of the intake manifold where the manifold and the head intersect. you can even pour water a long the same point. you should get an immediate change in engine idle/rpm.
