Pulled 1st Datamaster File 1995 Code H44
I will start reading up and have a basic understanding of all systems as this is not my 1st dance but certainly the 1st using this type of package. My goal was to hunt down an occassional ping, I do have a DTC H44 recurring, lean left O2.
I know the car was "richened up" per the previous owner when it had bored throttle, shorty headers and Corsa but to what end and how I do not know, only that it was all done by master tech at Chevy dealer no longer there.
Can some experts point me to which data they would be looking to 1st to begin. The o2 values go all over the place and not sure where to start with those.
