Well swapped the plugs to ones with better resistance and it still misfires like crazy. I even added a few temporarry ground strapes to see if that would help and it didn't do anything.
However I pulled the #4 plug out and laid it against some metal to see if it was getting spark and the car fired right up and even ran smoothly with that cylinder being dead. I then checked all 4 plugs for spark and they all have it. But when I put the plug back in it runs like scrap and misfires. I am thinking there is a ground issue with the ignition system. When I sent the distributor out it had that random ground strap that went under the cap. When I got it back it didn't have this anymore. I wonder if this is causing a problem. Though I did try clipping some grounds onto the distributor body to see if that was the problem and it didn't fix anything.
