A scan tool with a jumper wire? I don't recall needing a jumper wire for an OBD I scanner.

Ever notice that there's so many high performance parts available for GM products?

Did you ever think that maybe they NEED them?

I know you're a T-bird and not a Stang, but the troubleshooting should be the same.
