Thanks for the help,
No the engine coolant temperature sensor is not the same as the sensor that connects to the temp gauge in your dashboard. Another sensor is dedicated for this task. Both of these sensors are fixed into the cylinder head. I believe the ect is the one closest to the front of the car. In any case, if you disconnect the wrong one, your dash gauge will not work so that's how you'll know.

What you have indicated above might be a buggy thermostat. That itself could lead to big problems if it gets buggy the wrong way.

There is no choke in our cars.

Disconnect the ect and see if your car's behaviour changes. Its a 5 minute job. Bad ects are not always deactivated by the ecu, and can thus lead to strange engine symptoms. It is not likely at all, but since its so easy to test it why not ?


p.s. Please follow the steps I outlined in my first response to you as well.
