    P0171 and p0121 codes

    Hey, I was wondering what you guys thought about this. I have a 2000 Z28. Has F13 cam, Lid, K&N, Long tube Headers, Off road X, and bullets dumped. It is throwing a p0171 (system too lean Bank 1) and p0121 (Throttle pedal position sensor/switch A circuit range performance problem). Where do you guys think I should start looking?

    Any help is much appreciated ,

    Thanks,
    Bryon

    could be as simple as needing a new TPS and an O2 sensor.

    I replaced the TPS sensor already and reset the code and it still came back on
