Hello everyone, So Im quite new to the rx7 scene and don't know what's going on with my speedo it's vibrating like crazy, jumpy and ready very wrong x3 the speed. For the vibrating part as far as I know it's not a buzzer Because if I grab or push down on the pointer it will stop making the noise and I can fell it vibrating like crazy and for the speedo reading wrong it will be fine up to 10mph then it will go up at a exponentially high rate like 15 is 30, 30 is 50 and 50 is 80 or sometimes even higher I'm quite lost on this, any help is appreciated.

Some helpful info (it's a 1988 vert, I have not checked the cable yet and some buzzers have been messed with by the previous owner like the Shift and redline buzzer, not sure about the coolant buzzer or what the coolant even sounds like as this is my first Rx.)

 

I haven't tried this, but I remember reading about the issue before:

Thank you for the quick response I will check this out
