How to replace the Throttle body on a 05-08 Pontiac grand prix GXP. Power reduction due to OBD II Code P2138 ( Throttle/Pedal position sensor/ switch D/E voltage correlation).
I cleaned up the throttle body but the problem persist so I am replacing it for a brand new OEM Throttler body. I will update you guys after 2 weeks test drive on how the new part is behaving.
