Have a 2003 Fiesta 1.4 Duratec, it needs a new throttle body.

Currently it has the 2S6U-CC, tried two of these, causes the same issues

Called fords, they said it should be the 2S6U-DC

Tried throttle body off sisters car 2S6U-DB and it worked almost perfectly

Now I need to know, Should it be a 2s6u-dc or 2s6u-db

I can get hold of a brand new -DC but not a new -DB

Can anyone tell me the difference between these sub part numbers as well

Thanks
