OK, I just got my car back from having valve seals and gaskets done. 1 day later, get a check engine light. I had the code read today, and it says catalytic converter below threshold..WTF??

Either your cat, or post cat O2 sensor, unless you are having misfire issues or very poor gas mileage problems.

I agree with Dallas09 - same code on my car was post-cat O2 sensor.
