If indeed it is vacuum related, check all the CIS components, hoses, airbox and the injector seals. I found a hole in the metal pipe way around behind the airbox recently.
OPften ignition problems are mistaken for FI issues. Make sure your points, plugs, rotor, cap and wires are all OK.
How about compression and leakdown? Others may want to comment on this: could pulled head studs cause this?
