P1125 - Throttle Position Sensor Intermittent P2138 - Accelerator Pedal Position Sensor Circuit Looks like MAP sensor ... The Manifold Absolute Pressure sensor (MAP sensor)

Don't think it is the MAP but I pulled it off to check it. Came apart as I was pulling it out. Will replace and see. Had a lot of oily residue on the inside components.

MAP replaced. Still the same codes and reduced engine power and traction control warning lights. I can clear the codes but the come right back up when I put it in reverse.
