Sammy, to clarify:
-When the car is cold, if you disconnect the ISCV, the car will quickly stall, unless you plug the ISCV back in real quick.
-When the car is warm, as long as there is no heavy electrical load (e.g. cooling fans), disconnecting the ISCV should not affect the idle, when you plug it back in, the revs should rise a little, then drop again I believe.
