Coolant temp sensor can have a profound affect on fuel. If the sensor tells the PCM it is -40 degrees, it will positively DUMP fuel into the cylinders, and too much, is just as bad, if not worse, than not enough. If you have a scanner available that will do data logging, I would be real tempted to do a warm-up cycle while logging, and see what sensors do what.
It's always the dumb **** that gets me. It turns out that the connector for the coolant sensor was just barely connecting. Apparently all of the trials in Ouray (we covered 75-100 miles daily) caused that connector to work even looser. I disassembled it and pinched the terminals down a bit. Solved the problem, and the temp gauge now works.
I owe you a beer sir, and an apology for thinking I knew it all. Lesson learned!
