EGR vacuum lines

Long story short I’m trying to just disable my EGR temporarily while I wait to find a right manifold for my 87 to change the shitty clamp design EGR pipe.

I am blocking both ends of the EGR pipe itself - I know I need to plug the vacuum line from the solenoid to the EGR valve.

Someone else has told me there are other vacuum lines I need to plug - I’ve been staring at the diagram in the FSM.

Another newb question - when I plug a vacuum line do I plug both the hose and where it attached?

this car is my learning car haha

Just plug the vacuum line you pull off the EGR valve.

so there isn’t any other lines that go anywhere else that I need to plug? Solenoid? To the evap canister?
