Experts Needed. Accelerator Position Sensor or Throttle Position Sensor?

Hi Everyone,

So started having this issue two weeks ago after I installed a walbro pump, however I don't think it's related.

Out with my brothers two fridays ago and as we were leaving the restaurant my car has hessitates when I started it; car drove fine. Then, we made another stop and when I went to start it big time hessitation followed by sluggish acceleration as if it was going to die. The car was also making a backfire/popping noise from the front of the car.

Went to Autozone and no code related to that but, O2 sensors were throwing codes...had them changed along with PPE header install.

Still not fixed as of yesterday.

So went back to Autozone this morning after I made this video and got P1120 Accelerator Pedal Position Sensor. Can anyone confirm what my problem is with this video?
