Hello Everyone ! I have this issues with my 2006 Hummer H2 HUT model, the code P0120 comes up on the scanner ( Engine light comes on with " reduced Engine power " notice ) I have changed the pcm module and the gas pedal itself and followed instructions on resetting ( re-learning ) steps. so it will run fine one day, then i`m back to square one the nex day, same exact issue. It has been quite frustrating to be honest, wondering if anyone can offer help / suggestions and if anyone else has run into the same problem.
Much thanks appreciated in advance for any help offered !!

Tim
