I have a 2008 Range Rover HSE with 147,000 miles. I got a check engine light and the PID indicated catalytic converters in bank 2 were bad. I replaced the cats and then started getting P0171 and P0174 messages. I replaced the air filter and the MAF sensor and still getting the same messages.

The freeze frame info from the OBD scanner is as follows: Fuel System 1 CL Fuel System 2 CL Load % 47.8 ETC° 189.0 SHRTFT1 7.0 LONGFT1 12.5 SHRTFT2 -0.8 LONGFT2 10.2 MAP (inHg) 19.8 RPM 1322 VSS (MPH) 24 Spark ADVC° 33 IAT° 75 MAF (lb/min) 2.930 TP(%) 20.0 RUNTM (SEC) 157 EGR_PTC(%) 48.2 EGR_ERR (%) 0.0 EVAP_PCT (%) 36.1 FLI (%) 45.9 BARO (inHg) 29.2 VPWR (V) 13.964 Load_ABS (%) 42.7 EQ_RAT 0.961 TP_R (%) 8.2 AAT (°F) 54 TP_B (%) 36.1 APP_D (%) 28.6 APP_E (%) 28.2 TAC_PCT (%) 30.2

Can anyone tell me what to look for or what to replace at this point?
