Tachometer/Gauge Inaccuracies

When I'm idling or in neutral, my tachometer registers at zero. I know other people have said the gauges in YJs have been known to be inaccurate but I wasn't sure if the tachometer was included in that.

maybe you need to swap it out? is it wired right?

A lot of teenagers are people who express a burning desire to be different be dressing exactly alike.
Panties aren't my favorite, but they're right next to it...
No one is normal, there are just a lot of weird people with things in common.

Well it registers when I'm driving but I know by the sound of the engine that it's not registering correctly. For example, when she sounds like she's at 3k rpms, she registers about 2k.
