I have found that the 4-1 coil on the ignition pack is dopping spark. I placed a timing light onto the 4 and 1 cyl wires and you can see that both terminals are dropping spark. Above 1000RPM the miss is gone. I have checked wires, plugs, the coil itself, and the TPS. I still have to check the ISC as the idle will hunt on occasion so just maybe this could be the culprit. Any suggestions on where else to look? 95 Nissan 240 SX - SR Powered - 324whp@16psi 95 Honda Accord - H22A 191whp, 152tq. Melted Piston
