@drgnfly1900 - Did you have the error codes read again after the work was done? If so report the exact code(s) - format "P1234" If not, have the codes read again and then report them. Don't assume that the pre-work and post-work codes are the same - even though they could be.
Fill in the blanks on the repair. Did you go someplace and say "please diagnose and fix" ? Or did you go and say "this is what's wrong. Replace x part" ? If the former, what does the shop have to say that did the diagnosis?
There is a Ford TSB on the VCT system: TSB 03-15-14. These are generally not available publicly in full text. You can search the internet for a post of it, or a Ford dealer might get you a copy.
