i threw a p0171 (lean bank 1) a few weeks ago. i got many replies as to what it might be so i cleared the code and first removed my aftermarket intake. the code just came back and i'm thinking its my O2 Sensor.

so here's my question is it actually my O2? my car has 78k miles with the original sensor. if it is what replacement should i get? the $60 bosch from the auto parts store, oem, any online deals? i thoguht i had read somewhere about people getting them for $45 direct replacement.

o2 sensors should be changed every 60k give or take. and yes go with the bosch.
