Mazda 626 Sensor Problem

We have ran test on the car and keep getting trouble codes of p0171 and p0174, and are lean codes, could this possibly be the pcm, would hate to spend the money if we don't need to.
thx kathy...

O2 sensors not switching are correcting a overly lean condition May have intake leak, restricted air cleaner or clogged /dirty injectors
