Both rich and lean? That's got vacuum leak written all over it. Most probably, varying amounts of unmetered air are getting into your system. Usually vac leaks hiss or whistle, could that be your "whine?"
Do a quick visual inspection, follow all vac hoses from one end to the other. You'll probably find something's come loose. If that doesn't find it, a mechanic's stethoscope (a couple feet of rubber hose) can often help you pinpoint sounds. Or use a propane torch (unlit), when you get it near a vac leak the engine will change how it's running.
