All this reading on your P0420 and I popped a P0430 this morning...great...

Looks like I'll just be hollowing out the precat though since we don't have emissions testing here.

thats how that maxima luck is...hopefully the P0420 code is done now with the non-foulers. I had the P0134 come up but i cleared it and it hasnt been back since. Hopefully when I get this Magnaflow HFC, I can take the non-foulers out all together since I will actually have a cat installed.

Is this the first time you have gotten the P0420? How many miles on your max?
