Does the coolant temp sensor feed into the idle/fuel management system
somehow?  My temp gauge works intermittently, and I was told that it was the
sensor, but I haven't been to worried about it because I assumed it just fed
info to the temp gauge - does it do something more that I should be
concerned about???

Model:				1986 5KTQ  150km
Symptoms were:  	All of a sudden very rough idle, oscillating between
1500-1800 rpm.
Fix:				Replaced ISV
Symptoms are:		engine will not cold high idle...once it reaches
normal operating temperature, 				engine idles fine
-750rpm. Engine cold high idle worked fine before
troubles with ISV.
Tried:				Test swapped idle stabilizer temp sensor and
engine coolant temp 						sensor, both
appear to be working.
