Just read your story and saw that some codes are being set in the ECM. This sounds suspiciously like my wife's 91 L98 car - acted similar and after throwing parts at it, it was the ECM. They are not 100% reliable, and hers was randomly setting 3 unrelated codes.
I found one at a local junkyard and it was an AC Delco rebuilt. The 91 part crosses to about 10 other GM vehicles, and with a little luck you can find a used one to try instead of buying a rebuilt at full price. Good luck.

It's very misleading and incorrect. The only sensors on the side of the block are knock sensors and an oil temp sensor. Are you looking at a FSM for an LS1 or your 93?
