    4.6L Tech
    Hi all. I recently noticed the speedometer on my '96 Cobra reading way too fast, but only once in a while. I doubted that everyone around me on the highway was doing 90, and sure enough my GPS said 73 while the speedo said 90. But at other times, the speedometer is pretty much right on with...
