I replaced my catalytic converter and its' O2 sensor because the ECU light was given me the "catalyist below threshold" code. Now that the two have been replaced the ECU light still keeps coming on with the same code. I was then told that the new catalytic converter and O2 sensor are okay.

Is there anything else that could be throwing this code?

Could the O2 on the manifold need replacing too? (It is the original and I am now at 168K)?

Thanks for the help.

Could be, but first things first, did you clear the ecu? and the light come back on? Take the terminal off your battery and let the ecu drain for about 15 mins to reset if that wasn't done.

pull out the back-up radio fuse for about 10secs, that resets it

might sound kinda dumb but did you pull the battery cable yet? that reseted my ecu light.

something like that should reset itself. as soon as the issue is solved then then light should just disapper. unless you have a retarted ECU then you might want to try to reset it

It was the O2 on the cat that I replaced. Also, I reset the ECU with my scanner. The light comes back on shortly after I reset it.
