Having 420 code.Sprayed Cats down with SeaFoam.Didn’t get rid of 420 code but car ran better didn’t feel like it was dragging an anchor.Oxygen sensor spacers showed up put it on rear O2 Sensor Check Engine Light not coming on got emissions test passed and got new registration before the end of the Month and been over 2 weeks and no check engine light

New catalytic converter and new 02 sensors for my sons car. Check Engine light stayed on. I put the adapters on the lower sensors and the light turned off; passed the State Emissions test.

Works but check engine light will come on and off.. still helped me pass inspection thoe

Great product
