thank you for sharing this with me. I would never of known this and just assumed that my spark advance was haywire according to my data log. Tomorrow I am installing a new distributor with new ignition module and pick up coil as well. In addition, I am installing a new coil. I have no choice at this point to find this phantom, intermittent problem. My last effort is to believe that my coil is weak under load. I have went through everything from a to z a hundred times.... I will see what happens after installing these new parts tomorrow. say a prayer to the chevy TBI Gods....
They appreciate it if you sacrifice a Yugo or LeCar during prayers.say a prayer to the chevy TBI Gods....
