Update 2

The plenum is off. I found good and not so good.

The good:
All of the injectors test with 12.1-12.6 ohms resistance.
This is great news! Guess I'll have to eat that darned hat after all. Anybody have a good recipe?

I don't see any oil leaks down in there. Though there is some shredded insulation way down in the valley. I guess some critter once called that home?
This is more common than you'd expect. Something about this engine attracts those little critters.

Not so good:

Set up a free account with http://www.photobucket.com and upload the pictures there. Then cut and paste the links for the pictures into your post.
The online services like Photobucket automatically size the pictures for you so that they display correctly in a forum format.

It's common to find a little oil inside the plenum and also down in the valley below the plenum. Retorque the bolts to the breather box and check the hose clams on the breather box hoses (it's common for them to come loose). Give it a good clean under there, take the time to follow all the hoses and pipes and get to know what's going on under there. Check the secondaries for proper operation, all you need is one of those hand held vacuum pumps to apply vacuum in the appropriate places.
Hopefully JeffVette will chime in on the charcoal issue, there wasn't any in mine, but I have a '90, my systems are slightly different than yours.
