tachometer off
The tach on my camaro is off by like 500 rpms at idle and it gets worse as it goes up, like i have a 2.8 v6 and my tach will pin at 7000 and i still have rpms to go. Is my tach bad? is there some sort of adjustment? did my grandma who i got the car from have it rebuilt with 8000 rpm capabilities? probably that last one. what do you guys think?

Try this one, found using the search button.
There is another thread about the resister pack on the tach's going bad.
I had to fix the resister pack AND the capacitor to fix my tack. It was reading WAY off (resistor pack) and then it was only a little off (capacitor fix).
Hope this helps,,,
BTW...almost all third gens have at least one of these problems.
Your problem sounds like the resistor pack.
