2000 3.0l flex fuel engine is throwing P0171 and P0174. Replaced MAF, Egr Valve, fuel filter, fuel pump, pov valve, o2 sensor S2B1, fuel injectors and have done a smoke test and still getting the codes and it runs worse everyday. STFT is at around 30 after it warms up a bit at idle I have bank 2 trim at +or- 7 and bank one is at 24 to 30. o2 sensors seem to be changing voltage as they should at 1hz or once every second. Downstream sensor takes some time to show any voltage used to sit at .7volts going up hill or underload, but it sits at .1 now. Could I actually have a clogged CAT? Any ideas? Thanks in advance
