Put my foot down in my car today and lost power went into limp mode. Epc and traction control light on. Also the cel come on as well but went of when restarted. It's done this before about a month ago but turned car on the day after and every thing was ok. Had a look through the search and most people say its throttle body. Any clues before I book it in to get looked at. Maybe something simple I can check first.
