TAchometer Stuck

[89clubk]

I have a 89 240 with HUD, and when i bought the car, the tachometer was maxed out past 8 grand. As i accelerate it moves down to 6k, but when i shift it goes right back up. Is it just a bad ground or something?

does the cluster looked touched? if it is you will have to recalibrate it. those tach and gas needles are bitch.. they should never be touched

im not sure if it has been. all my other gauges work fine. will a cluster from an s13 without HUD work?
