Where is egr valve located on a 1994 Chevrolet caprice?
usually on the valve cover. it is a part of the emission control
system. it will most likely have a rubber hose attached to it. the
fix is pretty simple one you find the valve. hope it helps. duboff
take off the home plate look in the back towards the firewall it
has a vaccum hose on top of it its best to see from the drivers
