The only codes were P0420 and P0430 and according to my the code chart they both read: "Short to B+/upper limit/rich mixture Threshold"
Idle is great, no loss of power, no misfiring that I know of. At 62,000 I had the IMS, clutch, motor mount and coolant bottle replaced, at that time Precision Motion checked the AOS and it had been replaced and was in good condition. I do use a K&N but it's been 2,000 miles since I cleaned and oiled it.
Like I said in the above post, (4) new O2 sensors, 6 new spark plugs at 62,000 miles No oil burning, no excessive oil consumption no overly wild driving (I think?)
