Something to try before replacing parts. Clear the codes by removing the negative battery cable for 5 minutes with the head lights ON then reconnecting the cable and turning the headlights OFF then recheck the codes.

Which codes come up. If the same codes come up then something is wrong with the electronic throttle body.
