Just started up the 7 for a quick snack run, and the tach was bouncing around a bit, and was reading about 1000rpm too high. Once I got above 3000rpm or so it seemed to be okay. Back down below that, did the same thing.

Any thoughts?

Loose ground would be my best guess.

Kind of what I was thinking as well.

Where'd be the best place to start looking, is the next question . . .

Check your trailing coil connections. your tach pickup is connected there.

Thanks, I will check - of course the day my car decided to do this, and also lose the nuts off the manifold causing a gynormous exhaust leak, it just has to snow about four inches. Blech.
