I attempt to fix up my 2006 Toyota Corolla LE to give to my son; however, for past year the fuel economy of this car has fallen.
recently the check engine light came up and i pulled a code P0171 Bank 1 too lean; pulled freeze frame info: Shrtft 1 19.5 % and Longft1 26.6% and fulesys1 CL.
i struggled to find leaks (i think that is what i am looking for right)?
my question is where am i doing wrong and where is Bank 1???
any suggestion would be great.

depends on your engine.
V6: driver's side. Cylinders 1,3 and 5
i4: it's all the same bank
