More NF idle problems - more specific

[Eyvind E. Spangen]

I removed all the hoses on my NF engine today to check and clean them. They
were all fine. I messed around a bit more and discovered something:

When I first start the car with the ISV connected, it will jump straight up
to around 2000 rpm, stay there for a few seconds and then go down to around
400 rpms, sometimes stalling too. If I unplug the ISV, the car will idle
almost like it should, just a bit higher. (around 950-1050 rpm)

It looks like the ISV is causing the trouble. I've cleaned it and it looks
just fine inside, but is there a possibility that the ISV itself is broken?
