Hi everyone. I have come to get knowledge on my 2000 lc because I have a P0171 code and I can’t figure out what it is. I have replaced all O2 sensors and had reset but code came back 2 days later. I have had a evap leak before and I know I did not have the best mechanic in town. What would you guys try next. I haven’t gotten to cleaning the mas airflow sensor yet but I do have some readings from it. I uploaded 2 photos the one with .5lb was at idle. And the second photo is at 2000rpm. Thanks in advance!
