I have a used FICM out of a 04 f-350 from a used motor I put in. if your interested shoot me a pm. if you buy one through the dealer you will have a 12 month 12,000 miles warranty though. keep in mind you may have injector issues throwing them codes as well. best bet is to get it diagnoised and go from there.
