Blow off Valve

I notice today when starting my car that the blow off open for a bit then closes at idle. It will stay open for like 3 or more seconds that's not rite is it? I've been have stall out issues and hard starts followed by missing.

Normal it will open and then close as the idle comes down after startup, it does the same thing with lite revs at idle will open and close.
