Jim,
I'm still looking through the Workshop Manual for something that may be of help to you. I'm sure there is a trouble-shooter I can translate/get translated, but it's not easy to make the electronics stuff out, and a lot of it calls for a special Honda/Showa meter!
Silly question, but have you traced the coil wires back to the PGM to make sure there are no bad connections or any wires with cracked/broken insulation?
Andy.
