So I recently swapped in a 2006 engine into a 2004 Aveo. The issue I am having is with the routing of the PCV hose. I am using the intake manifold from the 04. Now Im not sure where the the hose goes from the PCV valve. I can google and see where it goes on the 06, and that's where I currently have it hooked up. But now the car is running with a high idle, and I think it's because there is an open vacuum port where the PCV hose is supposed to be attached...but I just can't find it.
