replaced the voltage regulator, fixed an alternator wire that mysterically got cut and was grounding to the frame, replaced the crappy coil wire that had terrible contact with the distributor, double checked the timing, tuned the carb, and even had the alternator tested
still misses really bad and runs choppy as hell
broke down and called my mechanic, he said the fuel pump may have lost it's pressure or something is wrong in the ignition somewhere cause the truck acts like it has erratic unconstant spark... who knows i'm at my whit's dealing with this retarded problem
