Bad AOS?

If the AOS is good the RPMs will actually increase but the motor will shutter a bit. A bad AOS the RPMs will drop, the motor stumbles and sometimes stalls. While the motor is running and you take the oil fill cap off does it sound like a shop vac at the opening? Put your hand over the oil fill opening, is there allot of vacuum (like a shop vac) grabbing your hand?
