Idle Stabilizer Valve Q's

[Matt Van Bogart]

My ISV is acting up again...I think.  With the wires attached to the ISV, 
the at-a-stop idle will range between 1000 and 2500 RPM.

Unplug the wires on the ISV and the runs with NO idle fluctuation.  Now my 
question is: is there a sensor that feeds the wires that plug into the ISV 
that could be sending the wrong message or is the ISV just not doing its job 
correctly?

Any ideas?
