I replaced it and it still don't stay running. I have a mallory unilite distributor with an inline filter. I wonder if the filter went bad? I also fairly recently soldered some of the connections together between the distributor and resistor because the plugs seemed lose. However I ran the car several times since doing that. I jumpered around those connections just now with some of those electrical connectors that just stab into the wires but the car still did not stay running.
