Anyone know the typical maximum spark plug wire resistance ( longest wire ) for a '92 Bonneville w/standard V6 ? ( I imagine any year that has the '92 style ignition system is the same. )

12k is pushing it. If more than 15k, replace it.
Cold resistance is not a fail safe test however. If you can't scope the wire under load, you really don't know for sure if it's breaking down or not. GW
Thanks friends. Happy trails.
Yes. Thanks, I forgot to say, "measure while hot." A scope under load is the best way.
