Bypassing egr question

[teamsmith]

So I have plugged the port on the bottom of the intake that goes to the egr valve but have so far left all other vacuum lines hooked up. What hoses should I disconnect and plug? Is it ok that I leave everything connected? I'm currently dealing with a hunting idle that bounces from 200-500 and wonder if this could be related. Thoughts?

any change with the line pulled?  have you tried wiggling all the vacuum lines while it's running?  tested the TPS yet?  cleaned the throttle body yet?

I have not cleaned the tb or the has sensor yet, it's on the list. I was more interested if there were any issue with leaving the egr lines all hooked up even though the port from the exhaust is plugged. I moved to an ho engine and used the ho exhaust manifold so I don't have a comparison of bedore/after. The idle is not bad but drops below 600, touches 200, the pops back up to 600. Running accesories doesn't effect it. I will definitely clean the tb soon and will plan on buying a plug for my egr valve port.
