P-0420 with Helix HF Cat
Today the "Service engine" light came on and it was P0420. So have others received this code with the Helix cat or might I have a leak? The tbe has been on the car for a couple months now and this is the first time this code came up. Thanks for any help.

Hi,
I have a random tech HF cat, and I also got the 02 code after a few months. I used the mechanical O2 fix with 1 spark plug anti-fouler and it hasn't come back.
Good luck,

Just put a Bob Marley CD in, usually takes of it. Actually, I have the UR Hi-flow and get it too. Seems to happen more when gas tank gets low. I just disconnect Battery cable to clear code.
