Tachometer problems 1989 IROC
The tachometer in my 1989 IROC is approximately 2000 RPM off. For example, when the engine is at about 3000 the tachometer reads about 5000. Additionally, when I turn on the turn signal, the needle goes crazy and bounces around erratically. Any ideas what would cause these issues?
