RPM Gauge

[mitchs_240sx_se]

it just started jumping after I accelerated quickly. It still moves but definately isn't accurate. Any ideas with what's going on? I'm gonna try to get Nissan to look at it for me, but I'd rather not have to hassle with them if it isn't needed.

All input is welcome...

...It's called a tachometer.Anyway...Does it wobble when it's going up or something? Why do you think it's not accurate?

the engine sounds fine, it idles fines and runs fine, the tach moves up to 2-4K RPM as soon as you turn the key to On, not even with the car running yet. It then wobbles back and forth whenever it feels like it.
