strong gas smell + black around tailpipe- leaking fuel inj?
codes and messages:
P0159 lambda sensor aging downstream bank 2
P0174/P0175 additive adaptive mixture correction tra bank 2
P0174/P0175 mixture adaption factor fra bank 2
P0150/P0152 lambda sensor upstream catalyst bank 2
Physical signs - a pretty strong gas odor while idling, running rich. Rough idle. Mpg dropped from 10/15 to 8/12. Also a very black and thick ring of soot around the tailpipe edge.
This can't just be bad O2 sensors?? Mechanic guessing I've got leaking fuel injectors. Could it be anything else?
