There are some very sharp poeple here, whom will give you their time and experience freely shared. Typographical error of one. Singular not plural. Discouraged? Welcome to the world of nobody has all the right answers. I gave you what you needed to know. Run wiith it. Good luck.

Here's a link to the factory service manuals if you're still looking. They're stickied up at the top of this section.

Thanks. I found them as well. I’ve got a lot of reading up to do. I’ll post here as the project progresses.
MAF cleaning tonight as well as some more vacuum leak searching around the offending cylinder.

Update:
Cleaned MAF
Changed out offending #5 plug
Checked Vacuum 17-18 hg
Cleaned up the easy to reach grounds I could find.
Used a can of starter fluid to check for vac leaks and found nothing.

Well I just took it 30 miles on the highway and on various driving and hills I have no misses or real note. There was a burst of them when I first got on the highway on #5 only (34 misses) and then not a single one since.

I’ll update the post if anything more develops. Thanks to everyone who helped and listened. This is a case of throwing parts at the problem and using the wallet wrench. I truly believed every step of the way I had it licked. ‍
