Several nights ago I cleaned the main ground, and re-plugged every sparkplug wire connector into the distributor cap. I also moved the ECU ground, and condenser and positive connectors on the coil so they don't bind or cross in anyway. 30 mile ride to friends house, and no issues. While talking to my buddy about AFM, and contemplating running a new ground from the wiper to the AFM male connector, we noticed that the wiper is a bit lopsided and barely touching the ground. Touching the wiper in a negative way, pun definitively intended, and the engine produced same symptoms of fuel hay-wire, and backfiring. A quick bend job, and now the AFM plug ground is making full contact with the wiper blade. No issues so far. Only time will tell how successful this was. I stopped by a gas station and got another 12.5 gallons of gas on about 200 miles.... not bad for a first tank of gas, and getting things all worked out and broken-in.... So far I have put 140 miles since the ground fix, and there have been no episodes of bucking.
