PO420.....so now what?

[eTiMaGo]

something wrong with the catalytic converter, i don't see how it can be more detailed than that

If there is a warranty on it, and if they don't revoke it due to the diesel incident, then do it!

well but then again doesn't that code MAYBE mean that? what about the maybe spark timing? or maybe a hose not sealed or a plug not tight, etc.
the code p0420 from what i have looked up seems to be a common one and one with one too many possibilities. but of course. warranty = $0 at least the last time i checked. also correct me if im wrong but toyota did say wrong plugs are in, well not the brand they want are in. so that would hopefully make this a warrantable fix. no need to bring up deisel being put in over a month ago and what not.
