Below is a test I ran with the torque app after I recently got an OBD II adapter. Worry a lot when it comes to my balt and there are a bunch of categories with 'Fail'. anyone know how to read this stuff? (P.S. Yes I know, noob, here.) Fails underlined for convenience

End of report.

 

I don't know how to read hex code, but most of the failed tests dont have a definition, and some dont make any sense. o2 sensor bank 4 sensor 4 doesn't exist. Your 02 voltages look good and passed, misfires passed etc. I wouldnt worry about the failed ones if you have no check engine light. Probably unused code. I dont work in an emissions state though, maybe someone with more experience with emissions testing will chime in.

 

Thanks for the incite. You're probably spot on that I shouldn't be too worried.
