[QUOTE="Kevin Palmer, post: 917260, member: 54263"] Put your original coil on and ses what happens. I have seen the 171 / 174 code come on with the installation of the SD coil. As mentioned, the 171 / 174 code is normally the elbow, but if you have replaced it, and assuming it is all connected still, then swap the coil out to see if the code will remain off once cleared.
