My temp gauge slowing starting going down and down and down and finally one day stopped working. Whats up? Is it a sensor gone bad? or what?...93 z28 by the way..Thanks guys

 

I was just about to search for this topic, mine did that like 2 yrs ago and i was just thinking i need to get this taken care of.

 

Check to see if the wire to the temp sending unit has come loose and the wire is making a good a connection inside the plug.. Temp sending unit is in the drivers side head... If that's ok, go HERE to shoebox's site and test if you have a gauge or sending unit problem.
