I was tinkering on the 95 Deville base model with the 4.9L last night. I noticed what looks like an empty vacuum port. There is a little bit of old hose or foam around the nipple where it looks like something used to be plugged in. Naturally I looked it up in Alldata but there are no vacuum diagrams and the tag under the hood doesn't show anything.

Hoping somebody could take a look at this car and see if there's anything there?

That's your egr solenoid. The filter is over a little port that relieves pressure to the open air. Rock auto sells those filters.

I know what you mean by how it looks like a hose should go on there but it's just what the foam filter goes over. Your all good I wouldn't worry. Maybe get a new filter for it or if you're feeling really flush throw on a new solenoid

Thanks! That's what I was hoping and makes sense because the residue looked like foam.
