Default Help With My EGR System!

I was finally able to start and drive my 1982 after a few months of working on it. Initially, all seemed well, but then I realized that it would die when slowing down. It didn't matter if the transmission was in N or D, so I was thinking it was vacuum related.

For fun, I tried disconnecting the EGR solenoid, leaving the vent open on the valve, and plugging the port on the throttle body. Problem has disappeared!

My question: Is EGR necessary on this car? What damage will be done if I continue to drive without the solenoid in place? How can I disable it completely? New solenoids are NLA and I don't think there is any other way of correctly hooking it up.

It won't hurt a thing disconnected.

I've seen some use "block off plates" or something. Is that totally necessary, or is ventiing to the atmosphere accomplishing the same thing? I'm really surprised I don't have a check engine light from all this. I removed both AIR solenoids and the EGR as well!

You unbolted the egr from the manifold? In that case yes you need a block off plate.

No, the valve is still bolted in. I was just curious if there was a difference between leaving the valve in place disconnected, versus the block off plate option.

No difference. The egr is disabled, so it blocks exhaust flow now.
