Right. I need to read mA current....
With the meter in series, the circuit is open. I can tell because the engine note changes when disconnected and it does not return when the meter lies in series....that is why I am a little confused over this harness.

I swapped a used distributor in and it was worse, but it was a junkyard distributor so can't tell 100%...
I really don't want to touch my 300TE's distributor, but at this point I need to 100% eliminate the distributor so I may go ahead and swap them and hope I don't make 2 issues out of one.

How can I eliminate plugged up cats? I guess its a possibility since the engine got very hot for that week...
