Ok I was driving to a muffler shop to have a test pipe made. The day before I took the bottom of the heat shield off the cat. I left the top on and put the bolts back in finger tight. Well today getting on the freeway I hear metal clanging on the concrete. Needless to say I knew exactly what it was. It cut half way through the wire for the secondary o2 sensor. Now no speedo and no v-tec. Did some searching I just need to would the cut wire cause both these problems?
