the sender for the gauge is NOT the Temp II sensor. The Temp II sensor sends
information to the ECU which uses this information to adjust the fuel
enrichment during start up.... The coolant temerature sender for the
temperature gauge is the other sender in the thermostat housing... at least
that's where it's at on my 90 Syncro.

I dont think so...

>is the sensor shot?

maybe the coolant temp sensor, but probably not the Temp II sensor...

why

the problem may be the temp gauge sender or the wiring between it and the
dash... or wiring in the dash or the bulb itself; but has nothing to do with
the Temp II sensor...

also before all

Temp II sensor can have effect on the idle via sending information to the
ECU....

It may be that you engine flooded by not having the Temp II sensor
connected... let it sit over night and try starting it again with the Temp
II sensor connected...
