Got CEL today

So I checked the code and deleted it.
Stayed away for a bit then came back. I deleted it again. Hasnt come back yet today.
The code is PCM P0430 H C.
So I looked 'er up and got this...P0430 TWC System Low Efficiency Bank 2.

Now I think it has something to do with the pass side coils, or plug wires or something? I took a quick look, everything looked ok.

Any ideas?
Thanks-In advance

are you running headers?
i believe the code is generally associated with high residual Hydrocarbon hitting the O2 sensor after the catalytic converter..... can happen with hi-flow cats
Either than our your cats are starting to get plugged....

o2 sims will solve your problem. try doing a search for member cbrf4i1, he has some o2 sims that will take care of your p430. i think i paid around $30 for a set.
update.....5k miles later, still no check engine light.
