Maybe not: some of the more miserable vacuum leaks happen only when the 
engine grows in physical size when it warms up. The bottom of an intake manifold 
runner, in the tappet valley, is such a place. Check your vacuum while running. 
Nevertheless, I agree that it sounds like carburetion. But the only other time 
I've run into this was on a long-distance diagnosis where it eventually 
turned out the newly-purchased Pantera's engine had a drag-race camshaft with 270 
degrees duration at 050 lift! Thus, 'idle speed' when warm was around 1500 rpms 
and idling it down at stoplights starved the engine, which always died. The 
fix was to add a street cam, not one for racing! Good luck, Dennis- J DeRyke
