Hello Vern & Ray, thanks for your replies. How does the simtec 71 actually determine an ignition misfire?Does it monitor the ignition primary waveform? or does it look at the lambda signal & crank/cam sensors to determine the exact time of mis-firing & which cylinder it relates to? I did check the power & grounds on this ecu by using a test lamp & found them to be ok .I expect that this one has a faulty ecu,the same as Tony & Ray have had,probably caused by the faulty coil.It would be interesting to know how the ecu determines a mis-fire though. Regards,Andrew
