with both of those codes those both are throttle body issues

when both are set either the throttle body connector is bad internally where the wires are crimped to the terminals or the throttle body itself is bad

the best action to take is to replace the throttle body connector and shrink wrap in the new wires to the existing wires one at a time to not mess up the wiring locations in the connector

if by chance it still does this i am sorry to say you need to replace the throttle body assembly to correct this issue

if you have any questions please ask as i do not get credit for my work until you rate us here at Justanswer
