Of those four codes, my 2001 Factory Service Manual only lists one, p1125, accelerator pedal position sensor. The accelerator position sensor is the housing at the accelerator pedal and has three separate sensors in it (for 2001). If any one of those sensors report out of range to the PCM, the PCM will set DTC p1125 and go to reduced power, your symptom.
I suggest you clear all codes and try again,note what comes back. I hate throwing parts at things, but the accelerator pedal unit is suspicious if p1125 comes back.
Anyone else out there with a reference to p2120 , p2126. p2131 or better ideas?

the others are for the tps circuit, could be a problem with the sensor itself or the wiring
