Re: Extremely High Idle
Not uncommon to have the Tachometer IC fail. Just replaced my whole cluster with a rebuilt unit, the tach was one of the issues. It’s a fairly straight forward fix if you have any electronics abilities or you can send it in. These guys will fix you up either way. Www.Batee.com.
With that high an idle you likely still have a vacuum leak some where. There are many possibilities. Here’s a good article by Marc Haibeck on the subject.

Good luck.
