I installed all new gauges recently. I noticed yesterday that when I'm holding a steady speed of 60 mph the needle rises up to almost 70, stays there for a couple seconds then drops back down to 60 again. It's done that a couple times. I have no clue if this a faulty speedo, loose wire, cable problem etc. I was hoping someone here may have heard of this and can suggest a fix.

Thanks
