Engine starts and idles but will not accelerate. I replaced the throttle body with 2 sensors (used), the mass airflow sensor, and the 02 sensor (used).
I am still getting 6 codes PO171, PO113, PO102, PO715, PO708, PO135.
I would first like to get the engine to accelerate and then fix the other codes.
Please advice.

PO102 - Mass Air Flow (MAF) Circuit Low Input

P0113 - Intake Air Temperature Circuit High Input

P0135 - Oxygen Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)

P0171 - System too Lean (Bank 1)

P0708 - Transmission Range Sensor Circuit High Input

P0715 - Input/Turbine Speed Sensor Circuit Malfunction

You have a bunch of things going on here. However, one bad part can cause a few other codes to set. Does the engine rev at all?

Have you checked the throttle position sensor (TPS)?

I believe you said it was a used sensor. It may be bad.
