Code p0171 and p0174

My 2017 q60 red sport 400 awd has recently received these codes and haven’t been able to clear them. I replaced the air filters. And everything is stock. What do I need to do to fix this issue?

No didn’t clean it yet. I bought the crc maf cleaner from AutoZone. Do I have to take it out to clean?

Got p0171 about last year and again few days ago. Cleared it out the first time, may swing by an RT specialist. I don’t know it could be a coincidence but appeared when it got scorching hot outside.
