Best bet though...use a separate O2 sensor as not to interfere with the
factory O2 signal to the PCM.

Subject: RE: DML: a/f guage help
had time to look at it today, the guage and sensor are fine. I'm on the
correct wire, my truck really just ran so rich the guage never moved. I
pulled fuel at idel with the apexi box and the guage eventually went

thanks for the help
