Missing wiring connector 94 D90

After chasing a 94 D90 flooding issue, a link led me to check the temp sensor near the thermostat that sends input to the ECU. Found that but no wiring is attached to that sensor and no unconnected wires in the area. This vehicle has been running fine for over 4 years without that connection. Still concerned about no codes showing and no check engine light. Injectors are definitely putting too much fuel at start but after start the engine will idle great and drive mostly normal except a slight misfire trying to accelerate in 4th and 5th gear.

The ecu puts a default value to allow the engine to run. It doesn't run perfectly but will run. It's called limo mode.

I believe the un-connect temp sensor you speak of goes to the a/c fan. Do you have a/c?

The temp sensor for the ECU is near the injector for the number one cylinder on the front left of the engine.
