OK, I got the AOS changed (not all that bad of a job) & cleaned and as much of the oil out as I could.
Questions I have so far are:
1. Should I run a can of Techron through to clean the remaining oil film in the intakes?
2. Would a failing AOS trigger the P0420 & P0430 codes?
3. Would the car sitting on jack stands for a few days on the front only cause this?
