I have a 88 CIS-e Roc'. I just changed the oil flange gasket, and the oil cooler O-ring to stop an oil leak, but it idles like crap now.
I pulled the ISV, and cleaned it a bit however, when I push up the little sliding valve (with a screwdriver) on the downward (outgoing?)port, it only closes about 85% of the way.
I'm suspicious cause I forced it closed the rest of the way, installed it, and it seemed to idle fine for a moment.
So is the spring in there supposed to close it all the way? I'm not even sure if this is the root of my problem though.

Ok, the root of my idle issues was the bottom rotten out of a breather hose.. no idea why it took so long to find that.
Anyway, the idle still is a little skechy. I don't wanna dump $$$ into an ISV if it's supposed to be the way it is.
Anyone know off the top of their head?

ISV rarely break never seen one that was shot... best bet is to ohm test the ISV with a volt meter use the Bentley it tells you how to do it.
