Re: Does a throttle body change require a PCM re-program?
Ford Tech here a bit late but will be archived. When changing to a new etb, disconnect battery for 10 min, replace throttle body, reconnect battery etb will sweep. Turn key on let sit 10-15 sec start car and let idle for another 5-10min AFTER it has warmed up. No accessories on i.e. headlamps,rear defrost, radio, havac, and etc... Fords will learn idle trim, gm's you need the scan tool. Another reason to love Fords!
