i would like to see the fuel trims , the long term & short term readings at idle .
and the oxygen sensor reading at idle ?
can you get those readings ,
if the cat is not finishing we have a problem , if the B1S2 is not reading or stuck at 0.9 volts or 0.1 volts , that should tell you cat is not working
i know they guaranteed it but if that is the case , that will the problem ,maybe its defective new one.
