The ground for the whole system and ecu is all on the left side of the frame under the subframe possible bad bond ? The ecu also has 2 power inputs pin 1 from fuse 1 fed by power relay, pin 14fed by fuse 2 and is constant +12v which is labeled for the fuel pump. There is a negative output to keep the power relay latched from the ecu pin 30 and is tied into the regulator rectifier which also shows the ground and +12v.I mentioned this to my dealer last week and they'd had a customer who needs a new reg/rec and stator to fix the same problem. Possible that on lower rpm the ecu is not seeing enough voltage across it to function properly?  If I unplug the ecu and reconnect it the problem goes away for a while.... just some ideas hope you get it sorted.Check the pulse generator too, sometimes a built up of metal shavings can confound it too.Lambda and map switch no, I've tried unplugging both.</blockquote>
