I experienced erratic speedo with misfire codes and o2 sensor codes. Number 15 fuse -- speed sensor blown. If it continues there is a common problem with this model year. Wiring harness located below air intake mainifold chafed. A bracket below the manifold is rubbing on the harness. If it is not too late, you can electrical tape, liquid electrical tape, re splice or cover with wire loom.
