1) Moved O2 sensors from one side to the other - Still get P0430 code.
2) Just cleaned MAF sensor yesterday - waiting to see if code will pop up again. Never know how long it takes. Was replaced 2 years ago. Looked prestine.
3) Recently changed air/oil seperator.

I am not sure how I could check for exhaust or intake leak - Will google that. I 'm thinking I need a smoke generator of some sort though.

paulv - I must say you've thrown me for a loop in many of your diag suggestions.

You obviously have much more experience than I do. Are the items you detail relatively easy to do once I understand what they mean?
