Yes it does have a cold start sensor. It is located on top of a throttle body.
Has the engine coolant temp sensor ever been changed.
Replace the engine coolant sensor.
The cold start sensor is the top sensor on the right side of the thermostat housing as you are looking at the engine from the front of the vehicle. It is 22mm.
Need to replace the coolant sensor. Not the tempture sensor.

Coolant Temp Sensor (CTS) if its more pronounced on cold days - this is the 2 wire sensor - NOT the one wire sensor - the 2 wire sends input to the PCM (computer) and the 1 wire is for the dash light/guage. Eric The coolant temperature sensor is a common problem for these cars. I would be suspicious of it. When my Saturn wouldn't start on cold days it ended up being a computer chip. This chip also controlled the shifting. My car had problems starting in cold and shifting at first when cold.. once computer chip was replaced, there has been no problems.
bad cooling sensor or bad connection at cooling sensor.
Yes, a faulty coolant temp sensor can do that.
Start by checking the temperature sensor for the computer
Its the cold start fuel sensor giving you troubles. Its flooding the engine with fuel.
From a cold start, yes it can.
