What does the hose on the passenger side of the throttle body do? It runs from the tb to the valve cover.

It's on the passenger side. It goes from the passenger side of the TB to the passenger side valve cover. It's an oil vapor vent tube IIRC.

its just a fresh air hose for the pcv system. some people will cap the port and just run a breather so i doubt that will cause an idle problem

The hose uses intake vacuum to pull out crankcase gases from the crankcase and reintroduce them for combustion.
