I have an 04 Murci (orange/black) with CEL, high idle & 4 codes: P2196/P2197/P2198/P2000. The 2197 is a O2 lean code and the other 2 are O2 rich codes. The P2000 is NOx absorber efficiency below threshold. 97 and 98 bank 1/sensor rich & lean. Vehicle has 2500 miles. Any have experience with these issues?
