Lets be more accurate..

P0171 is System lean Bank One .. Sys lean is is likely because the Intake you put on is too big.. and the MAF Voltage coming to the ECU, does not match what it will call 'Normal'.. and It's having to add too much fuel..

That is not a 'Rich/lean' ... it's a you screwed up the Calibration of the MAF by the Aftermarket Intake thing.. Tototas really like Stock Intakes..

The Injen intake isn't too big
