HA!
I think hes saying that you cant get them new. You can go to a junk yard a see if there is a wrecked 2001 Focus you can take the throttle body off of. Search ebay, or any other online store that may have it.
Also, was this from a dealership? or a smaller repair shop?
I'm kinda skeptical that there is absolutely NO 2001 Focus throttle bodys laying around.
John Deere provides me with brand new parts for a 1949 tractor.... there shouldn't be ANY part you cant get for a 2001 anything.

There is one on ebay, but it seems kinda sketchy.. only one picture and it's a generic picture at that. If you decide to bid on that part and it is a scam, you can not hold me accountable for it. Be REALLY careful when perchasing anything online.
Good luck.
