code again

About 3 months ago my LJ produced code P 0431. I started reading about it on here and tried tightening the exhaust manifold bolts. I got the code cleared and it didn't come back until yesterday. Next step?

Your code could be one of your mini-catatytic converters has gone bad(The ones by the exhaust manifold). One of mine had a hole burned through the catalyst material. I had the same symptoms as you. I could go 2-3 months between it throwing codes.

How did you determine that was the cause? Is there something I can look for?
