    Hey guys got a 99' Classic with a 60 series in it. It has developed an intermittent miss. She puffs a little white smoke when it misses. Its happening about 6 to 7 times a day. Fuel mileage hasn't changed, it isn't using any coolant or abnormal amount of oil. The only code it is showing is a 46 which I believe is:

    46 168 - 1 ECM Battery Voltage Low
    46 - 214 1 RTC Backup Battery Voltage Low
    46 - 232 1 Sensor Supply Voltage Low

    Don't know if the codes above mean my ECM is crapping out or its got a bad ground somewhere, they seem to look alright but you can't see a broken wire I guess. I replaced a few fuel lines because they where looking a little old but that didn't fix it, there are no visible fuel leaks, the fuel filters have been changed twice.

    Any help would be appreciated:biggrin_25514:

    Check your five pin power plug ( 2 positve and 3 ground ) - follow the power harness back to your fuses and to the batteries , your looking for a broken wire , corroded fuse holder or corrosion in the harness

    It ended up being a corroded fuse by the batteries. Replaced the fuse holder, cleaned the battery terminal and its been running fine for a couple of days. Thanks
