I have a 2014 Chevy Silverado 1500 5.3L V8 with 112,000 miles...Initially had issues with Fuel tank sensor...never replaced it.( but will be soon as it comes in) then I kept getting OBD codes telling me to replace O2 sensors that they were failing or running rich...so I did. Check engine light went away for about 100 miles....then engine light came back on and I now get new codes P013D (heated oxygen sensor(HO2S) 2, Bank 2 slow response lean to rich, P2097(Post Catalytic converter fuel trim (FT) Bank 1- too rich ,P2099 (Post Catalytic converter fuel trim(FT) Bank 2- too rich...( also replaced Mass Air Flow Sensor) I have no clue what to do. Other than having a mechanic look at it. Unless a miracle happens and the Fuel Tank Pressure sensor fixes the issues. Also, other day it felt like it wanted to stall out when I came to a stop at a light. put it in neutral and revved it up a little then it was fine. Seems like it has a low idle. Any help would be great!
Thank you
