Replacing tune up parts was just general maintenance. Car starts up fine and does not miss until completely warmed up. Then when driven it misses. Replaced coil as it has samed symptoms as one going bad, also cleaned fuse box and replaced fuses, all ground wires cleaned and any suspected wires repaired. I had another 78 that had no fuel pump noise when key turned on but when running could hear pump--it ran great and this one is the same as far as noise goes. I am not very electrical minded and do not have the tools to do current checks, and I think this is one of those problems, but I would like to be wrong on this point. I thank everyone for there help on this.
