Has anyone every come across a problem with the ignition ECU, in which it was working but seemed to do weird things, such as miss fire occasionally or make the tach flicker? Also since the Ignition ECU has a ground within its wiring does it need to be grounded anyway? Does anyone have experience as to what the effect would be if it were not grounded. Thanks, Dave Delman D² & 6530 Still trying to track down that elusive tach flicker at idle which goes away when a 2700 ohm resistor is placed in series with the pickup coil...
