You could try stopping the intake vacuum getting to the charcoal canister from the cold start pipe. This is how I did it on mine, and it lowered the idle back to normal. Pretty easy too!

The manual quotes the oil dipstick tube and oil filler cap as sources of vacuum leak...maybe look there (o-ring on oil filler?), otherwise I'm running out of ideas for you.
No chance your sealant fix on the idle pipe has melted? FWIW I have the stock pipe and fitting and it still idles on spec when warm so it can be made to work, even though it looks and feels like it will leak.

I have cleaned the inside with brake cleaner and compressed air about a month ago.
But i have never checked if the thing actualy works! Car is in pieces now, i will check it once everthing is back together.
Is there a way to trigger the valve to see if it moves? Just run the car and let it warm up?
