I had a 1976 Volkswagen Rabbit that had a squeaky tach cable in college - it used to drive me crazy. Then a new roommate who was a car guy moved in and did something to lubricate it and it never made noise again. I hope it's that easy of a fix. To look on the bright side - we've all learned a lot from reading this post.
