More pictures, show and tell...
In an attempt to further eliminate any guess work on my part, I went ahead and finally after 17 yrs completed what is the rights of passage for any Delorean owner, I ventured into my Valley of Death. Figured why not, I'm so close to it, might as well finish taking that air intake off.
I was surprised the valley looks pretty clean, I have a bit of oil in the crannies , likely from a clutch slave I replaced a few years ago. I will clean it up before patching everything together. My vacuum connections seems pretty good, and rubber hoses were not cracking or brittle. So that checks. I also will assume all those switches and sensors in the Y pipe are good to go too, as I heard their failure rates are low. But if anyone has some neat way of checking them with a multimeter, please let me know.

What I was mostly concerned about, was the condition of my intake ports on the engine and valves. Lots of black deposits caked all over the place. The engine has 44K original miles. Is there anyway to clean this stuff up on the surface at least at this point? I intend to use regular Techron cleaner from now on to help. But what is the general diagnosis on this type of condition? Although I don't believe this is the reason for my car not performing one day to the next, it is obviously a concern to me.
Here are pictures of my cylinder intakes:

Finally, here is the inside of the air intake side, all black .
