Well yes it is lucky Rich can remember the code but as a future guide for members from a Master Technician with Ford:

Re rich's problem: "his problems may be related to the CHT sensor (Cylinder Head Temperature)" .. but, of course, as he hasnt seen your ST he cant say thats it for sure but its a suggestion for you incase it happens again

Re deleting fault codes: "Don't let anyone read and delete these codes , take it straight to your dealer and let them read them print them out and get your case started. Oh and no once them pratts delete them they're gone!!!"
