1997 dodge neon parts help

Prescott AZ

Description

Just bought this car and it's got some oddities the first thing is there's a hose attached to the back side of the valve cover and it leads to a spark plug???? Does anyone know where that's actually supposed to go and maybe even have that hose part for sale... Then the second thing there's a hose fitting on the underside of the hose that goes from the filter box to the throttle body that's just open to the air....
