Yes I have changed coil, coil wire, CDI, cap, rotor, distributor.
AFR's go nutty but consistantly low when the bucking starts. Yes I checked the fuel system first when the problem started and all was in spec. The control pressures have been adjusted on the high side of spec to compensate for a weak rear pump that is showing system pressure on the low side of spec. I plan to change out the rear pump if I ever get that elusive 18m/16m fitting.
Thank you all for the help and ideas, we WILL get this solved. I'm planning to drag the car over to the shop soon as my time for this has expired, gotta move on.
