Code?
The other day it was about 95 degrees (if that matters) and after about an hour drive and a short stop the check engine light came on.
It appears most codes are history.
But one code says PO171 which is fuel trim system lean bank 1.
What do you do about that one?
Thanks.

Yes it's only PO171.
I do have a halltech filter that I oil lightly once/year.
Took that off and sprayed it with an air hose but it didn't seem excessively oily?
Also sprayed off the screen which seemed very clean.
Clear and monitor I assume?

I cleared the code and will monitor.
Didn't see any other signs of a problem but I'll have a closer look when I can.
Thanks for your help.
Edit: Also, stock except for the air filter.
