Throttle back idle problem...

For several years, my 87 9kT has been faultering when falling back to idle from almost any open throttle position. The tach drops to about 500 rpm, the engine stutters, then it shudders back up to 12- or 1500 rpm and settling back to around 1000.
It did this before and after a valve job, and it goes away briefly after replacing the plug wires, plugs, and cap and rotor. But it always returns shortly after. The boost gauge holds steady, so I don't suspect any hose leaks, but should I? Where else can I look?
TIA for your help.
