Rough idle when warmed up

I'm trying to figure out why my engine starts to stumble and runs rough when it's warmed up. When I start it cold, it sounds great. Sharp engine pulses, sounds tight. Then, after it warms up, it starts to run like crap. Stumbling, shaking, low vacuum. I checked everything and I can't figure it out. Any suggestions?
