            That's so true... my ignition coil was fried and everything and I changed everything before I finally changed out my optispark... and low and behold that fixed my misfire lol

              Well..What happens when a 94 Z28 gets a dirty orange spark because the Opti is fried? Just replace it too? the guy already replaced the distributor..cap...button...plugs..wires..map sensor...ignition control module..msd coil pack. Still wont start.. I'm thinking of buying this car if thats all I have to do. lol

                          i personally went through 2 ACDelco optis and 3 el cheapos from auto zone. I eventually went MSD...BUT YOU HAVE TO REMOVE THE OVER AND LOCKTITE THE TWO SCREWS IN THE ROTOR BUTTON, THEY DO NOT PUT LOCKTITE ON THEM DURING ASSEMBLY, THIS IS A MUST AND SCREWS BACKING OUT OF THE ROTOR BUTTON IS THE MAIN CAUSE OF THE DISTRIBUTORS CRAPING OUT. 3 out of the 5 distributors that went bad i could shake and hear the rotor button flopping around. ACDelco and distributors from parts houses can not be disassembled to do this to my knowledge.
