RPM drop

I changed a new hose for the AAV. On my car, is there a fuel pressure switch or air pressure switch or regulator? It almost feels like it is loosing fuel or air pressure when RPM goes down. I cleaned up the WUR and the lf hole was very dirty with deposit so I cleaned it and use compressed air to make sure that it is debris free. The diaphragm is still in good shape. I was just wandering on the AAV, when it is cold it is 1/4 open is it normal or is it suppose to open completely? As you know there is a little slit opening weather it is open or closed. If it continues I will have to do a fuel pressure check.
