Follow up. I installed the new plugs and coil packs. All is well again. The coil packs that I removed tested fine. Everything was clean and in excellent condition. I think one or more plugs went bad. Thanks for all the advice and help.

Great news, and thanks for the update!

Did any of the (rear bank especially) coilpacks exhibit any corrosion at their bases?

Zero corrosion. You could not tell the new packs from the old ones. All the bolts looked brand new. My car has lived a sheltered life.

This is a picture of the rear bank plugs and packs I removed.

The coilpack surface(s) I'm asking about with regard to corrosion is on the backside, where it contacts the head (see photo link)...

No corrosion, the entire coil pack looks like what you see in the picture. My guess is the plugs gave out after 23 years, as the packs tested fine and dont appear to have any visual issues.

That picture you linked looks like a lot of corrosion!

That's good news! Thanks for letting us know how it turned out.

23 years, as in those are the original plugs? If so, perhaps time to check on any other deferred maintenance items.

Yes, original plugs. The car only has 23k miles.

Timing belt, water pump, belts, were done several years ago. All Fluids changed regularly.
