Sounds like you found the vacuum reservoir.
As for the Top-Engine Cleaner, if you did it right, you can rule out carbon build-up as the cause of the "pinging". The timing chain is possible but you should also look into anything that could be causing a "lean" condition, and make sure your EGR system is functional.

Could be possible that none of that stuff was ever checked..... It would be something that needs to be done, but may not change the ping.... I just replaced the air filter FOR THE FIRST TIME today on the fleetwood, it had NEVER been changed after 36k!!! It was black and icky.. Thats what they get for letting a private shop take care of all the maintenance....
Kat, can i get this TOP ENGINE CLEANER at any cadillac dealership???

Yes sir, you can.

Then I may have to go pick up a can before i take things apart for cleaning :) . I assume it would effectively clean the plenum and intake manifold too....

yah , im almost at that point , no code for the engine tho , just the damned torque converter ,and a keep alive memory loss
since id think the torque converter would need replaced ill wait untill the damned converter is laying under the car in two peices
im kinda thinking it might be the soleniod for it but im not even gonna pull the pan off to do that yet , maybe in a few months when im ready to mess with it again
