check engine light stays on and this morning "reduced engine power" flashed along my dash and the gas pedal wouldnt work. I shut it off and restarted and it worked.

got a problem with the fly by wire system. you need to go to a shop and have it diaged and get a bide. either a pedal sensor or the throttle body.
