P0171 error code

Hello everyone,,
Not long ago I was noticing a rough idle at a stop on my ‘16.5 GT. Idiot me thought the battery might be going since it seemed to stop after running for a while.
Well, today the check engine light came on and a quick scan revealed the P0171 code ‘system too lean’ - a quick google and I discover that a rough idle is one of the most common symptoms so it would seem this is all related mobdro bluehost kodi.
Further investigation leads me to believe that this is a fairly common error code on the CX-5 and so I’m wondering if anyone else here has run into this code and what the issue wound up being. TIA.

First thing to check would be the MAFS sensor, remove and clean it, there are several videos on youtube you can watch.

Sometimes this happens when the environment changes drastically enough to cause the learned fuel trims to be out of spec. I have this happen driving across country simply by getting to a hot and high environment. You can check basic stuff such as filter/maf as good practice, but I'd unplug the battery to reset the long/short term fuel trims
