if your cat and O2 is screwed for the second time, maybe it's something more related to what's coming from the engine...should look into the codes, maybe there's more

Is that LA as in Los Angeles or LA as in Louisiana?...I have the tool if you can wait until the Huntington meet in Sept 10, i'll be glad to bring it with me

Well put. If you got a p0420 again...then something is destroying your cat.....
