Hello peeps i need some help i have an f20b im running the jdm h22 intake manifold with a 2 wire iacv i have always had idle problems i do not have any coolant lines hooked to it, is this necessary for proper operation? if so how are they routed thanks in advanced.

 

if anyone cares i found the answer

The IAC valve is supplied heated water, via two small coolant hoses, to keep the valve from developing ice during cold operation. The IAC valve is not sensitive to the temperature increase from the heated water. The position of the IAC valve's plunger is totally dependent upon the amount of time the ground is on, which is controlled by the ECM.
