sorry for your plight !!
CEL out running? check engine light out?
its rich misfiring, and probably not holding closed loop at cursing (Sigmund Freud was here).
The oxy sensor is not working (is exhaust head tube 4 cracked) or bottom header collector donut gasket bad, sucking in air?
it may be in limphome mode, too.
is MPG bad? (horrid)
1: IS ENGINE FULLY HOT, 180f MIN?
2: is CEL out.
3: is 02 new? less than 100,000 miles old?
4: is exh. cracked or leaking before the CAT.
5: huge air leak in the total air intake path? examine with eyes, there can be no leaks behind the FAM sensor or it can go lean.
is the ECU flashing code 12?
