Idle problem.Thought fuel, but it was bad ECU

adriver,
67Dart273 is our resident auto electronics expert. He has been studying the Mopar ignition boxes for a few years, pulling them apart for death forensics and reverse engineering. A noble cause, that helps us all, and great automotive design archaeology.

Many FABO guys who just want to "get er done" and don't care about originality have converted to the superior GM HEI module that doesn't require a ballast and lets you run a better coil. To each his own. I am in the HEI camp, but my Mopars are all 1960's models so no conflict over originality. Any e-ignition beats mechanical points.
