Nope. No cold start valve.

Running richer makes sense. Always seemed "flooded" if hard to start warm.

I should pull a spark plug or two and see what colour they are.

Though not mentioned in my first post, 2 of the 4 wires from sensor
are flawed. The ground wire on ECU portion, and one wire on temp gauge
"side". Neither should be an issue I *think*. Ground would be
redundant and temp "side" not in use. (AFAIK, this wire runs straight
to connector for Jetta instrument cluster) I'll wait to see if swapped
sensor cures problem, then I'll repair the wires.

Nope.

Swapped in the other ("VW") ECT sensor. Seems to run the same. Time
will tell if ECT DTC shows up again.
