i just had my 07z twin turbo'd and everything was fine but my check engine light came on and the code is PO123 - Throttle/petal position sensor/switch A circuit high input. it seemed to only throw the code when i was at open throttle and let off. any help would be greatly appreciated. thanks

 

try the throttle body reset

 

i did just try it and its still throwing a code. its nothing machanical because the throttle bodies are working fine and i would imagine if they werent working then i would be throwing more than just one code. but its just this one.
