I had the forced emission patched flashed onto my ecu recently. When we read the Emission monitors with a code reader, they all say Ready/Pass. The problem is I still get the P0420 code. I have a straight pipe (no cat) and the rear 02 sensor is still hooked up. Anyone have any idea on how to get the SES light to stay off? TIA
