I did the whole vacuum line's mess, and have that back together. And it has made the idle smoother.
BUT... it smootly varies over a few hundred rpm worth. As if the ICV wasn't responding rapidly enough.
It seems to work if I apply 12V directly to the terminals, that being I can cycle the valve by switching the ground from the two side terminals.
And I did spray it out with solvent, and blew it out with air. So I believe it to be pretty clean.
Is this worth replacing or should I check something else first.
