Thank you for reading all that and replying. Iīm stuck in Mexico at the moment and wonīt be home for a few days. I will look for the other sensor you mentioned. Iīm all for replacing sensors. Theyīre cheap and if they havenīt failed yet they probably will soon.
I still wonder why the symptoms disappeared when I reinstalled the old CTS. The CTS harness is a mystery in and of itself. I canīt trace it far before it disappears under the fuel rail. It maintained the 4.2 volts even when I wiggled it around so I donīt think it shorted.
