Lower Coolant Sensor

[Cade Carvell]

Hi,
  In the quest to determine my wierd inconsistant idle problems (87
4KQ), I started to check sensors.
  While I had the engine running, I pulled the conector off the lower
coolant sending unit, and the engine exihibted very similiar issues as I
had seen when the car acted up.  Obviously it was worse, the engie
barely ran, dash lights started to come on and off, etc.
  Is this normal?  I would think that the computer should go into some
kind of closed loop, and limp.  I let the car do this for 30 seconds,
then realizing that it would not even out.  Pluged back in the car came
right back.
  Since I noticed a little bit of green coloring, assuming that this is
were my slow leak in the cooling system is, I am going to replace this
part.

But should the car die like that, or is there something else that may be
wrong, and this just helped point it out.

Thanks again everyone,
