Hi, hope someone can give me some help. I have a 1995 Heritage Softail. The bike recently started acting up and now is only running on one cylinder. Initially had after market plug wires with a ground on each one. The ground came off and thought this was the issue. changed to new wires then ran well for 30 mins started running on one cylinder again. changed single fire coil and tested single fire ignition. Now will only run on rear cylinder right away.

 

Swap wires only runs on front,coil
