RE: [DMCForum] Re: [DML] No power at 4000 RPM

["Travis Goodwin" <tgoodwin@xxxxxxxxxxxx>]

I've got an old analog dwell meter and I may have just gotten lucky on the
O2 sensor. I am not 100% sure of which holes to plug into on the
diagnostic
socket. I was using 2 and 3, one is the lambda circuit and one is the ECU
(ground). I put red into the lambda and the black into the ECU ground. 

Am I doing this correctly?
