Engine missing weak spark

Hey all! My 79 930 has a low rpm miss and hesitation. I thought fuel related for the longest but I have investigated from both fps, filter and a/f ratios. It appears Im getting fuel, It runs strong when I get on it but has a miss a times at low rpms and cruising. Sometimes its better than others. I have changed the coil, plugs and wires replaced, cap and rotor was inspected, not by me though. I need some direction on what else can cause a weak or irradic spark. Distributer? Anyone else experience something simular? Thanks, Mark
