Title: Question re: ICV
Post by: pbgd3skier on June 06, 2010, 07:36:43 PM
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.
