Let me start off apologizing if this is somewhere else, I have failed to find an answer with the

search function. Okay, I've had this cluster for few years and it went through 3 preludes, on

it's third now. The cluster has 222k on it and everything was working 100% until recently.

The Tach. and/or MPH will randomly fluctuate sometimes alone, sometimes together. The

Tach. can go off as far as 1500-2000rps, the Speedo. can go off as far as 25-35mph. Now im

obviously not going from 90-110 in a second flat, is this a common problem? Is this fixable? is

this messing with anything? The ecu pulls numbers from the dizzy right, so it should not really

be affecting anything but my nerves correct? Any input is helpful, thanks!
