Ok heres another bug I need to figure out. Just got done with my v6 to 4.6 dohc swap w. t-45, and took it for a test drive today and noticed the speedometer and of course the odometer isnt working. anyone had a problem with this before? Im hoping its just the spped sensor. But im just wondering if it could be something else. The check engine light came on after awhile so I put my tuner on it and it couldnt see any codes? so i clicked the clear button and then the light went off, but i know its probably going to come back on since the speedo isnt working. just looking for some opinions from others that had this problem before. also, all other guages are working properly. Tach, temp ect.
