I found a catalytic converter service bay test on a 2007 Buick Lucerne 3.8l.
This is a first time for me to see that. Does anyone know about this
or could this really be an Evap Service Bay Test?
I have seen some bad info data lately on 2008 Camry 2.4l (tmmk)
where the The words stated: AFS (Air Flow Sensor b1s1) Voltage.
Should be corrected as (Air Fuel Sensor B1S1)
